I realize this isn’t all of my characters, but these are the ones who specifically are pet owners and thus of course really like most animals!
Also in the boat of “liking most animals” is Addy and Esteban. (Surprising, I know.) Desma likes them if they’re well-trained or really really pretty to look at (and will secretly make exceptions for bad training if the pet is super-friendly, as well). Ashley and Ace can both kind of take ‘em or leave ‘em - that’s not to say that they HATE animals, but they just aren’t in their realm of interests. You won’t catch either at the zoo or in a pet store.
