Caturday: Do Felines Fart? Plus: Happy Human, Happy Cat Study

Do cats roar from the rear? Scientific American investigates feline fecal fumes and fart frequency.

Continuing its mission to probe the greater enigmas of the natural world, and knowing many of us must have pondered the question, Scientific American has set out to determine whether cats break wind.

In what it calls “an investigation into the mysteries of feline flatulence,” the magazine confirms that, yes, our furry friends do pass gas.

The good news? They are infrequent cheese cutters with minimal ass acoustics, particularly compared to the notoriously flatulent canines.

The bad news? When cats do fart, they are silent but deadly (SBD) affairs that deliver maximum olfactory potency due to the sulfurous mix of proteins and amino acids broken down by their digestive systems.

I can personally confirm that factoid, having been on the receiving end of a particularly insidious squeaker while Bud was sitting on my chest and nuzzling against my face. Once second I was rubbing the top of his head and telling him what a good boy he is, the next I was nearly gagging.

Farting is a normal biological function for cats, veterinarians told the magazine. While New York-based Cat Practice’s medical director, Eric Dougherty, says he doubts “anyone’s ever measured the exact quantity of cat farts in a scientific study,” you should have things checked out by a veterinarian if your little pal’s getting insane in the methane with concerning frequency.

“If you’re coming home and your cat is ripping farts every day,” Dougherty said, “you probably want to have it looked into.”

Same study, different interpretations

A few weeks ago we wrote about a Japanese study that found oxytocin levels spike in cats and their humans when they’re in close proximity.

The chemical – which is essential for bonding and often corresponds to positive feelings – rises in our respective bloodstreams when we’re interacting, the research team found.

Interestingly the effect is tied to distance, or rather lack of it. That means if your little buddy is bonded to you, you’re both at your happiest when you’re next to, or in physical contact with, each other.

The study didn’t find causation, just correlation, and the standard “we need more research” caveat absolutely applies here.

While the research team went to the effort of observing interactions in homes where cats live, and of testing cat and human urine samples for real data on biochemical levels instead of relying exclusively on questionnaires, the sample sizes were small. The team collected complete data on only 24 cats and 17 people.

It also found an unsurprising link between negative human moods marked by higher cortisol levels and stress in cats. That makes sense, as we’re extremely important to our feline friends. We’re the ones who care for, feed, shelter and love them, and they’re highly attuned to our emotions.

VICE, which ran a story on the study on Nov. 5, had a different take, claiming the study found “the oxytocin levels of humans and their cats appear to rise and fall in sync.” That’s not exactly what the paper describes, as negative human emotions were found to precipitate lower levels of oxytocin and higher stress hormones in cats. Again, the paper doesn’t establish causation, so we’re left to infer that our negative emotions are the catalyst without hard proof.

A handful of other publications published articles with interpretations similar to those of VICE, while a story by phys.org concentrates on the proximity aspect and notes that it could account for why different research teams have had varying results when trying to figure out whether having a cat leads to greater happiness.

This Caturday we look at how pets fare in domestic violence situations, plus a study about obesity in meat-eating and “vegan cats.”

The headline is a quote from a text a man allegedly sent to his girlfriend after abusing her cat so badly that the poor kitty had to be euthanized.

The story is grotesque, tragic, and sadly not uncommon. Between 75 and 89 percent of domestic violence victims who have pets report that their partners threatened, abused or killed their companion animals, according to research from the ASPCA and SafeHouse, a non-profit that provides direct support to victims of domestic violence.

In the incident referenced above, an Indianapolis man was arrested and charged with killing a domestic animal and torturing or mutilating an animal, both felonies. The suspect, Rashawn Bentley, originally tried to stage the violence as the result of a break-in, but was undone by his own menacing texts to his girlfriend as well as photos of the injured cat, according to the local NBC affiliate, WTHR.

Just so it’s abundantly clear how we feel about this issue: if you abuse, harm or kill a cat, you’re not a man. You’re a weak, despicable, cowardly facsimile of a man whose “flex” is taking your frustrations out on an innocent animal one twentieth your size.

You should be arrested, charged with the most severe penalties under the law – even if they’re not commensurate with the horror of the crime you’ve committed – and imprisoned for years. The other inmates should know you killed a cat. You should be removed from society, because if you think taking life is an acceptable way to vent your frustrations, there’s something clearly wrong with your brain and you are a danger to animal and human alike.

Of course the majority of these attacks, especially targeting cats, are committed by men, but women aren’t off the hook here either. Some women do try to harm significant others by killing or abusing their cats, in straight relationships and relationships between women.

Ignore that study on supposedly healthy ‘vegan cats’

Headlines about a new study in Frontiers In Animal Science are trumpeting the supposed benefits of vegan diets for cats, who are obligate carnivores.

The media stories style the effort as a large-scale study involving more than 1,300 participants.

In reality it was an online survey that recruited cat caretakers from Facebook and recorded their subjective opinions about the health of their cats.

Everything, including reported weight, mobility, questions about potential physical problems, times fed per day, sex and neuter status, et al, was filtered through the self-selected respondents, not pulled from veterinary records. The respondents weren’t given reference illustrations or standardized criteria from which to base their subjective assessment of their cats’ weight.

There’s no way to determine if the people who participated were being honest, keeping records, guesstimating or just having a bit of fun.

To be clear, most of our criticism here is directed at the way online publications reported the results, not necessarily the authors of the survey, who chose a much more dry, cautious headline: “Impacts of a vegan diet on body weight and related health disorders in 1,305 cats: an exploratory cross-sectional survey.”

Obviously, even a jazzed-up version of that honest headline would never be used by click-chasing modern media.

Notice the bottom right headline, which misinterprets a statistical analysis for “odds” of being overweight.

Ninety percent of the people who responded were female, and 71 percent were from the UK, according to the published paper.

Then the authors kneaded the data with the usual opaquely-named practices: “exploratory regression analysis” (a data-mining technique), regression models (AI-assisted statistical technique that involves comparing existing data with the result you predicted/hope to see), sensitivity analysis (changing variables to assess their impact on the overall findings), and so on.

When all was said and done, 4.1 percent of the meat-eating cats and 3.1 percent of the vegan cats were over their ideal weights, in their humans’ estimation. Meat-eating cats were also more likely to be underweight (2.3 percent) compared to vegan cats (0.8 percent).

The conclusion? The findings were “non-significant,” the researchers wrote, along with the obligatory call for more research on the topic.

We should also point out that in addition to their classification as obligate carnivores, cats require specific proteins and nutrients (taurine, arachidonic acid, vitamins A and B12) from meat-based diets that they cannot synthesize themselves and are not found in plant-based protein. “Vegan cat food” must have those proteins and nutrients added. If cats are deprived of them, they suffer slow, painful declines that result in organ shutdown and death.

Because of their evolutionary history, cats aren’t as adept at breaking down plant-based starches and their bodies don’t produce enough of a specific enzyme (amylase) that breaks down starch and complex carbohydrates.

Human ideas of morality aren’t applicable to cats. Feed them meat.
