I already do have an island which has a mix of rabbits and cows, but I voted for the rabbits in the poll.
If I had an island that only had rabbits, these are the following that I'd choose:
I voted for cat because I made an all-cat town in New Leaf. Though I didn't do much with it after collecting all the villagers lol
If I were to do it again in New Horizons, this time I'd choose:
Lazy: Bob
Jock: Stinky
Cranky: Tom
Smug: Raymond
Normal: Mitzi, Kiki
Peppy: Merry
Snooty: Purrl, Olivia
Sisterly: Katt
I'd also be interested in making all dog, frog, and penguin islands! My main New Leaf town almost became an all-penguin town by accident when 3 of my 5 starters turned out to be penguins
I had an all male rabbit island once of Sasha, Toby, Cole, O-hare, Claude, Hopkins, Gaston, Dork (Doc), Genji, and Snake ♡
I don't think I could ever do a Monospecies island ^^; I only really vibe with male personalities, and I really don't want a sisterly, personally not a fan of them.
I had one. I flattened the island and regretted it, so I reset on my own switch and now I’m unsure if I want to keep some of those villagers or hunt for Rosie and Ankha.
I chose cats because I'm a cat person, though the thought of having Raymond on my island makes me feel weird. I like his design, but his stans have left a bad taste in my mouth when it comes to him. I would've picked frogs, but really Tad and Lily are the only 2 frogs I like. I do want to do a mono-species island one day, but I'm not sure how well I'd do it. Especially as a chronic resetter.
I chose pigs because they're the only species I have 2 of on my island currently and I think they're an underappreciated species that deserve a lot of love.

Either Cat, Dog or Frog; this is after going through all of them and seeing which I would like more. And these ones had more of my favourites and nothing I HAD to add like the others. Or like one villager out of them all were what disapointed me more, say for example Sheildon in the Squirrels.
