i'm the type of person that likes animals in general, so i can say to myself it would make sense for me to want a pet as an animal companion.
i have a cat in the house, and i like the cat, cat's as relaxed and sleepy as i am, although he's not the friendliest.
but i've always been more of a dog person. i've liked dogs for as log as i can remember, and i think having at least one dog when i live alone will get give me my fix of companionship. Might get another one so that the dog doesn't end up lonely when i've left to go to work or something.
i also liked snakes, and considered one as a pet, maybe if i don't get a dog, although a dog would be a lot more receptive to things like commands and such.
i also wanted a pet fox. Specifically, Siberian domesticated foxes are being sold, and since i love foxes, i wouldn't mind a pet fox around. Super expensive though. the steep money used goes to science though, so that's a plus.
