I think all of these qualities can be found in a lot of animals, but we tend to stereotype them. I've known cats that are extremely loyal and caring, and dogs that are loners. XD I would totally be down for more Cap transformation fics of any type though, because it's always Tony that gets turned into a Cat and the others having to deal with him. I want to see Tony having to deal with an animal.

Steve would have to have a really stubborn mare of some sort if he's got a horse. <3
