I'd start with my dog and my grandmas cats. My neighbor's got a variety of dogs, including a half wolf and retired police dog. The police dog was retired because it was shot in the leg, so he is about 3 or 4 years old. I could morph him and be uninjured. There are deer and elk aplenty in the mountains. My friend's family owns two horses, a race horse and one they inherited from someone in FL. I mean Cassie proved horses are useful in #1, right? Forget about breaking in a zoo and risking suspicion, i could just volunteer once at the local zoo and BAM. Lion, elephant, rhino, worlds largest rodent, and a lot of other things you'd find at the Denver zoo. Yeah, some of the animals you get to pet. I could also just stop by my sister's job and find a huge amount of avians, whether they are predators or not, since she works at some bird sanctuary. Racoons and foxes, are often captured by my backyard neighbor and set free in the middle of nowhere, so I could just ask to check them out.
I've got a ton of places for pretty useless morphs.
