Who knew there were so many Olivers?
The Dickensian moniker tops a new list of 2020’s most popular male cat names, followed by Charlie and Leo, two names with regal connotations. You can’t throw a dart at a history book without hitting a King Charles, while Leo conjures images of the famed Spartan King Leonidas as well as panthera leo, aka the African lion, often mistakenly called the king of the jungle. (Tigers, not lions, occupy jungles. They’re also the largest cats on the planet.)
Rounding out the royalty-themed names are Simba (at number seven), the eponymous Lion King, Loki (at eighth-most-popular) of son-of-Odin Asgardian fame, George (10) and Louie (13), as in Louis XIV, le Roi Soleil, the Sun King of Versailles.
Here are the top 24, which might seem like an arbitrary number until you read through the list:
- Oliver
- Charlie
- Leo
- Max
- Jack
- Milo
- Simba
- Loki
- Oscar
- George
- Ollie
- Jasper
- Louie
- Simon
- Henry
- Dexter
- Toby
- Winston
- Gus
- Finn
- Kitty
- Tiger
- Rocky
- Buddy
Yep. Buddy’s not sure if he should be insulted at the lack of recognition, or happy that the feline Buddies are an apparently exclusive club.
The list was compiled by Rover.com, a site that allows people to connect with pet sitters and dog walkers. The list is based on the most popular names of cats belonging to the site’s registered users.
