A California biologist who shot and killed 13 cats as part of a “predator management program” referred to the felines’ corpses as “party favors” in a celebratory email to colleagues, according to a copy of the email.
David “Doc Quack” Riensche, a senior wildlife biologist with California’s East Bay Regional Park District (EBRPD), used a 12-gauge shotgun under cover of night to shoot the cats, documents obtained from the EBRPD show.
Riensche and EBRPD knew the felines were part of a colony near Oakland Coliseum managed by Cecelia Theis, a local woman who provided them with veterinary care, food, water and conducted TNR (trap, neuter, return) services to prevent the colony’s population from growing.
They did not warn Theis that they were going to cull the colony late last year, nor did they reach out to contacts in the area’s extensive local shelter and rescue network to trap and remove the strays, despite repeatedly stating that shooting cats is an absolute “last resort.”
“Good morning Lisa and Jeff,” the email from Riensche reads, dated Nov. 18, 2020. “I recently cleaned up more than a ‘bakers dozen’ of party favors in this resource protection area. With the conclusion of this wildlife management action, I am seeing some really good birds starting to re-colonize the area with the limiting factors now removed. Have a great week.”
Riensche, who disposed of the dead cats in trash bags that he tossed into a bin, signed off the email about the dead cats with a smiling emoji.
Although Riensche uses coded language in the email, the district’s own records, Riensche’s overtime statements for overnight hours, timestamped audio of dispatch calls and EBRPD’s own timeline of the cat killings all line up with the date of Riensche’s email and a spreadsheet documenting when and where Riensche shot the colony cats.
Tiffany Ashbaker, a volunteer with Alameda’s Island Cat Resource and Adoption, said she was horrified when she read Riensche’s email describing the dead cats as “party favors.”
“I was disgusted. Way beyond hurt,” said Ashbaker, who helped Theis trap, neuter, vaccinate and relocate the Oakland colony cats. “I find this to be unethical and he should be removed from his position at EBRPD because of it. I understand why we should try to have cats further away from the protected areas, but how they handled this was eye opening for sure.”
The cats lived between two auto dealerships in an industrial area separate from the MLK Jr. Regional Shoreline, a park in Oakland managed by the EBRPD. When Theis returned to the area to feed the cats on Nov. 3 2020, she realized several were missing. Over the following days more cats began to disappear, Theis and Ashbaker noted.
When Theis asked EBRPD about the whereabouts of the colony cats, a district staffer told her EBRPD wasn’t involved and didn’t remove any cats. EBRPD then amended its response, saying it had trapped the cats and brought them to local shelters.
But none of the local shelters had any records of taking cats from EBRPD, nor did they have the missing cats in their care.
EBRPD admits its biologist killed colony cats
Theis went to KGO, a local ABC News affiliate, and when a reporter began asking questions about the missing cats, a spokesman for the district finally admitted one of its employees — later identified in documents as Riensche — had shot the cats as part of the “predator management program.”
Theis said she felt “a horrible feeling in my gut” when she realized why the usually friendly strays and former pets of the colony were suddenly skittish. Riensche shot the colony cats over a series of nights, returning to the park in the late hours with a shotgun to kill two or three at a time.
Theis said she now understands why the remaining cats were so fearful and skittish when she came by for their regular feedings. One cat named Sherbert jumped on her car hood, and two others meowed insistently at Theis, “trying to tell me.”
“I feel this horrific feeling that they went through terror and were trying to tell me,” Their said. “They weren’t eating like they did usually.”
Some EBRPD board members have expressed sympathy for what happened, Theis said, but she described being “depressed” and worried because the district won’t give her any guarantees that it won’t kill more cats.
“We feel horrible about this, you know, this is really one thing that’s just really sad,” Matt Graul, the EBRPD’s chief of stewardship, told KGO in December, after the public first learned the cats had been shot.
Despite that, EBRPD ignored public records requests from the TV news station, and a spokesman for the district defended the cat culling, saying it was necessary to protect endangered birds who winter in the nearby marshlands.
Stray and feral cats “are not part of a healthy eco-system” EBRPD spokesman Dave Mason said, claiming his agency was protecting endangered wildlife in the area.
Public and animal rights groups demand an end to cat killing practice
After intense public backlash, including a petition with 70,000 signatures protesting EBRPD’s actions, several district board members were quoted in media reports saying they would end the practice of killing cats and would demand an investigation. Almost five months later, the district is instead moving ahead with a plan to contract cat-killing (and the culling of other animals like foxes and opossums) to a federal agency, and there has been no investigation.
Ashbaker, Theis, the non-profits In Defense of Animals and Alley Cat Allies, and local shelters have all demanded EBRPD stop killing animals entirely. District officials continue to argue it’s necessary to protect endangered birds, despite a lack of scientific evidence supporting the idea that arbitrarily shooting animals has any measurable impact on bird populations.
EBRPD has made one concession: It’s promised to reach out to rescues and shelters in the area for help removing cats before making the decision to deal with them lethally.
“While we’re pleased that the policy seems to be to work with local advocates as to prefer not to killing cats, we want to see a pledge that this never happens, ever again,” Fleur Dawes of In Defense of Animals said in February.
The district “should have been up front from the beginning, saying ‘This wasn’t what should have happened, [so] let’s make it right,'” Ashbaker said.
EBRPD has been unable to provide proof that the cats were killing birds on the marsh or that Riensche shot the cats on district property.
In response to a public records request for any documentation of cats preying on birds in the marshlands, EBRPD produced a single document from 1992, noting one incident with one cat about 35 miles south of the MLK Jr. Regional Shoreline where Riensche shot 13 cats in late 2020. During a survey some time before 1992, an EBRPD employee saw an example of “[California Clapper] rail predation” by “what we determined was a feral cat, in a marsh in the East Palo Alto area,” where it says “many cats are found.” The document mentions another cat that was sighted swimming “in flooded tidal salt marshes” in south San Francisco Bay, likely “foraging” for an endangered mouse species.
The district has not been able to produce any written guidelines or protocols describing how its employees determine if a cat should be shot instead of being relocated or brought to a local shelter, except for a vague summary of minutes from a 1998 meeting during which they claim the policy was approved.
EBRPD has been unable to produce copies of the cat-killing policy itself, despite several public records requests seeking that document.
In addition, in internal emails after a KGO reporter began asking questions about the cat killings, several EBRPD staffers questioned whether they have any documentation saying cat culling is an acceptable policy.
EBRPD internal discussion: Are we following our own rules?
In those same internal emails, which were obtained from EBRPD via public records requests, staffers wondered if the district was following its own rules requiring it to reach out to local shelter networks and receive approval from federal authorities to kill cats. One EBRPD official, assistant general manager of public affairs Carol Johnson, noted the document EBRPD used as justification “does not mention dispatching these animals,” and requires the district to “work with animal rescue organizations to help trap feral cats.”
“[The] question is, are we following the protocols listed in the document?” Johnson asked her colleagues in a Dec. 2 email. “I would argue we are minimally following through with the organizations and we have nothing to say lethal means is acceptable.”
Internal correspondence among EBRPD staff, obtained via a public records request, show worried staffers searched in vain for a written policy on killing cats before using a Google search to find another agency’s policy.
EBRPD finally produced a copy of minutes from a 1998 meeting with notes attached saying the cat-culling policy had been approved by the board, but if a copy of the policy exists, the district has been unable to produce it.
In December Mason said cats were only shot as a last resort and “[L]ethal removal only happens when feral cats are in the act of hunting wildlife on District property,” but none of the documents say the cats Riensche shot were hunting. Indeed, it would require an extraordinary stroke of luck for the biologist to find 13 cats preying on endangered birds in just a few nights.
Despite public records requests, the EBRPD was unable to provide proof that Riensche had consulted anyone before shooting the cats. Records indicate no one was notified until after Riensche killed the animals.
In addition, the cat colony sat some distance from the protected marshland: An office park, electric car charging station, at least three parking lots and a substantial body of water are between the cat colony’s home and the marshland. That’s a distance considerably longer than most stray and feral cats range from their homes, and domestic cats are notoriously averse to water or getting themselves wet.
Records line up with cat shootings
While Riensche uses coded language by referring to the cats he shot as “party favors” in his email to colleagues, it was sent on Nov. 18, the day after EBRPD’s own records show he killed the last of the colony cats. Internal documents from the EBRPD, obtained through public records requests, as well as the district’s own public timeline of events, show the dates the cats were killed line up with Riensche’s email. In addition, in audio recordings of his radio contact, Riensche advises dispatchers only after he’s fired the killing shots.
“Yeah this is Dave Riensche in wildlife at MLK, I just dispatched an animal down here, so if you get a call, it was me,” Riensche tells a dispatcher in one of the calls on Nov. 13 at 6:24 a.m.
EBRPD’s records show the only animals killed on that day were cats.
(Click the embedded audio to hear Riensche call dispatch on Nov. 13, 2020.)
Finally, according to EBRPD’s records, Riensche received overtime for working on nights that correspond to the same dates EBRPD says the cats were shot. [EBRPD document: TIMECARDS (REDACTED)]
Riensche, who has been employed as a biologist with the district for decades, is a prominent birder whose work involves protecting birds and other endangered species from predators wild and domestic. He penned a newsletter, Bird News, in the early aughts and is on record saying there’s “a wealth of evidence” that stray and feral cats are the primary danger to bird populations.
Shooting cats as a ‘first resort’
Riensche earned $182,951 in salary and benefits in 2019, the most recent year for which salary data is available for public employees in California. Riensche earned a base salary of $90,239 and $56,050 in overtime, including for overnight hours spent shooting animals in EBRPD’s parks.
An Oakland woman who wrote to the EBRPD after the district came clean about the cat killings related an anecdote about Riensche from 2019.
The woman worked with a local rescue that received a call from a parks employee who wanted help trapping and relocating a female cat and her young kittens who were living on or near an EBRPD park. The rescue volunteers were working with the EBRPD employee, making plans for the cat and her babies to be vaccinated and spayed/neutered, and even had homes lined up for some of the kittens, the woman wrote in a Nov. 25 email.
After visitors to the park saw the mother carrying a dead rabbit back to her kittens, “Doc Quack [Riensche] then reportedly told employees he was going to shoot the cats,” the volunteer wrote.
The mother cat “disappeared” and her fate was unknown, but the rescue was able to work with the EBRPD employees to get the kittens trapped. However, Riensche wasn’t happy with that outcome, she wrote.
“I was told later by an employee, that they were reprimanded for saving the cats and going outside of the EB Parks, to get this help,” the woman wrote in her letter to EBRPD. “Apparently, they should have just been quiet and let Doc Quack shoot the cat family.”
The connection between birders and cat killing
Cat killing isn’t unusual among birders. In 2007 a Texas man named James M. Stevenson — founder of the Galveston Ornithological Society — admitted killing dozens of cats on private and public property after coming to believe the cats were killing piping plovers, shorebirds who commonly nested in the area.
An article in the Los Angeles Times noted Stevenson wasn’t coy about what he’d been doing:
In a 1999 posting on an Internet bulletin board for bird lovers, Stevenson nonchalantly described killing many feral cats during his first year living on Galveston Island. He rationalized his acts as a way to restore the natural order.
“I’m sorry if this offends — but I sighted in my .22 rifle, and killed about two dozen cats,” Stevenson wrote in his message, titled “killer kitties; kittie killers.”
“This man has dedicated his whole life to birds,” Stevenson’s attorney said in his defense. The case ended in a mistrial.
In 2011, a wildlife biologist employed by the Smithsonian National Zoo’s Migratory Bird Center was found guilty of animal cruelty “for sprinkling poison atop cat food intended for feral cats living in Washington, DC.”
Nico Arcilla, then known as Nico Dauphiné, was well known as a birder and outspoken critic of cats. A group of people who cared for strays near Washington’s Meridian Hill Park contacted the Humane Society after noticing food they left out for the cats “would sometimes become covered by a white powdery substance overnight.”
After the Humane Society and Washington police tested the substance and verified it was poison, they set up a stakeout and had cameras trained on the food bowls. Footage, which prosecutors later exhibited on trial, was damning:
“Dauphiné [Arcilla] can be seen approaching the bowl, pulling something out of a small bag, reaching down toward the food twice, and then leaving the scene,” a sciencemag.org report reads. “The next morning, police found the food covered with the same white powder as before, which tested positive as poison.”
[Click here to see video of Arcilla poisoning the cat food.]
Arcilla wasn’t just a prominent birder and anti-cat campaigner — she is a co-author of several frequently-cited studies claiming cats kill billions of birds in the US each year. Those studies, which have been used to justify cat-culling policies around the world, are highly controversial, with critics blasting them for poor methodology, a lack of hard data, and arbitrary numbers plugged in to estimate both the national cat population and the felines’ impact on birds. For example, the authors estimate a national stray and feral cat population between 25 and 125 million, an estimate so vague that any extrapolations based on those numbers are virtually useless.
Riensche has repeatedly cited Arcilla’s work in public and private documents arguing that cats are primarily responsible for declines in bird populations.

There’s a petition (linked in the article) with some 70,000 signatures asking EBRPD to stop killing cats and other animals entirely, and to make it official policy that the district works with local rescues and shelters to trap any cats that make their homes too close to protected areas. (The rescues would then check for microchips, vaccinate, spay/neuter and find homes for the cats. We know some of the colony cats that survived turned out to be missing pets, and some were reunited with their people.)
EBRPD is also going to discuss and vote on an official policy in a future meeting. People can politely reach out to board members and kindly voice their opposition to any policy that involves “lethal removal” or “wildlife management actions,” which are the polite terms some conservationists use for the practice of killing animals in a misguided effort to protect other animals.
I know regular readers of this blog are awesome people who would articulate their thoughts constructively, and I hope anyone else who leaves feedback with EBRPD’s board will take a similarly diplomatic and constructive approach. I think we all agree that cats should be kept indoors, for their safety as well as the safety of other animals, and strays should be taken in, cared for and placed in good homes.

I am the colony caretaker at Oakport. The article that stated the cars were owned is a lie. Each time I trapped a cat to spay or neuter, I check them for a microchip. I then put a new microchip on them because none of the cats at Oak Court belong to anyone. Martinez snap get an article that is a complete lie and I have been fighting to get that article taken down. I was upset to see the article posted on petition as it was a lie.
Great article, I believe every word, but knowing the public they’ll probably defend him and cite that Smithsonian article again and again. Some will even call him a “hero” and “helping the environment”, it’s crazy so many people believe that study. and the media has just promoted it more

Thanks, Samuel. There’s really nothing to dispute. All the information comes from records obtained via the California Public Records Act, and from publicly-available data. Since EBRPD is a government district, it’s subject to the same open records laws as, say, your local city council or police department.
The most relevant source documents are all linked in the article, included as scans, photos, PDFs and audio files. I’m happy to share more, I just didn’t want to overwhelm readers with links to hundreds (thousands?) of pages of material. Sorting through that stuff, finding the relevant information and working it into a readable format was really the challenge here, and I had the help of some dedicated and determined people.
That’s one reason why I added the new index page that will be the permanent home of all EBRPD-related stories and documents. I’m hoping it will make it easy for readers to get background and context on this issue, and to take a deeper dive into the source documents if they choose to do that.

Apparently this happened at the NJ shore years ago. All the ferals were removed (how, I don’t quite know) but once they were gone, the area became overrun with rodents, many carrying diseases deadly to birds and other wildlife. ,

I just saw an article about a similar situation in Australia where there had been a major effort to eliminate cats. Apparently there’s been an almost biblical explosion in rodents, sweeping through the area in their millions, and people are freaking out.
And of course there’s the worst disaster of all, the Black Plague, when cats were almost completely extirpated from Europe and rodents were allowed to multiply unchecked.
I’m certainly no expert on ecosystems, but cats do seem to have a role in the balance of things, at least in and around areas where humans live. At the same time, I think birders can find allies in the majority of cat caretakers who understand it’s better to keep pets indoors, for the health of the cats as well as local wildlife.

It’s truly difficult news/information to consume; this creepy California cat hater is bad. To me, though, also particularly worrisome are the unfavorable attitudes toward cats openly expressed by news-media commentators, whose recklessly worded views can be influential.
The editor of a B.C. community newspaper wrote a 2018 column about courthouse protestors demanding justice in 2014 for a Sarnia, Ontario cat shot in the head 17 times with a pellet gun, destroying an eye; within, she declared: “Hey crazy people, it’s [just] a cat.” The court might have also perceived it so, as the charges against the two adult perpetrators were dropped.
Elsewhere, an otherwise progressive national columnist twice (of which I know) openly stated her dislike for cats.
In one of her (then called) Metro News Canada syndicated columns, Vicky Mochama proclaimed, “I never liked cats”. In another, an Oct.30, 2017 opinion titled “How to silence heckling MPs in the animal House”, she wrote that Canadian politicians should replace their traditional unproductively rude heckling with caterwauling: “My vote is for meowing because I don’t like cats and I’d like to sabotage their brand as much as possible. So if our elected politicians are going to be disrespectful in our House of Commons, they might as well channel the animal that holds us all in contempt.”
I search-engined the Internet but found nothing to even hint as to why she so publicly dislikes felines. (I’m pretty sure their reptilian-like vertical slit pupils and defensive fanged hisses do not help their cause.) I also sincerely asked her, via Facebook private message, why she feels that way, but I received no reply. As for my own house cat, Simon, I feel he does not hold me in contempt but rather appreciates me as much as I show my appreciation for him.
Nonetheless, the above-mentioned callous contempt for cats might reflect on why feral-cat Trap/Neuter/Release programs are typically underfunded by governments and private donors, regardless of their documented success in reducing the needless great suffering by these beautiful animals. About three years ago, it was reported that nearby Surrey (B.C.) had/has approximately 36,000 feral and stray cats, so many of which are allowed to suffer severe malnourishment, debilitating injury and/or infection by callously neglectful municipal government as well as individual residents who choose to remain silent. When I made a monetary donation to the local Trap/Neuter/Release (TNR) program, a lady volunteer left me a tearful voice mail expressing her appreciation, which to me suggested a scarcity of caring financial donors.
It’s as though there’s a prevailing mentality of feline disposability; a subconscious human perception that the worth of such animal life (if not even human life in regularly war-torn or overpopulated famine-stricken global regions) is measured by its overabundance and the protracted conditions under which it suffers. I feel that only when over-populations of unwanted cats are greatly reduced in number by responsible owners consistently spaying/neutering their felines, will this beautiful animal’s presence be truly appreciated, especially for the symbiotic-like healthy relationships they offer their loving owners.

Recently, I contacted Surrey Community Cat Foundation regarding the status of the city’s approximately 36,000 feral and stray cats, very many of which are allowed to greatly suffer by a callously neglectful municipal government (as well as individual residents who choose to remain silent). I was informed that, if anything, their “numbers would have increased, not decreased, in the last 5 years.”
I was also informed that the problems continuing for feral cats and strays in Surrey are:
• The increase in population and the lack of interest by more residents in caring for strays.
• Lack of affordable pet friending housing causing cat owners to leave their pet behind and outdoor.
• Tear-down of older homes where there was feeding done by the resident or the neighborhood.
• New construction and lack of places for ferals and strays to go.
• Lack of City participation in reducing the suffering of all the cats (ferals and strays) by providing funding for a City veterinary hospital including low or no fees for low income spay/neuter.
• Increase in residential housing and condos with developer fees not being put toward the care of misplaced feral and stray cats on the land.
• Lack of cooperation with City services that are unable or do not want to care for stray cats that are not tame.
• No place to house trapped feral cats.
• Barn locations must be checked out and meet high criteria for the care of the animal. Colonies cannot be maintained without a resident caretaker and a food supply.
We can go a long way towards stopping ailurophobic freaks by replacing the unscientific data with reality: #1 cause of species loss is HUMAN caused habitat destruction. http://www.alleycat.org/resources/humans-the-number-one-threat-to-wildlife/
As a media professional, I find it deeply disturbing that the Marra studies are reported and repeatedly cited without an ounce of skepticism, especially because they’re not actually studies and there isn’t a whiff of academic vigor. They’re essentially screeds masquerading as research, with no relationship to reality, using invented statistics to blame cats for species decline caused by humans.
But the biggest tragedy is that these studies are used again and again to justify animal abuse and the extermination of cat colonies. They provide cover to people who want to kill cats, and the authors have not taken responsibility for the actions they’ve inspired — in fact they’ve doubled down.
You have to wonder how these people sleep at night.
