Do you have a decided preference between cats and dogs? Which do you prefer, and why? Would you consider a roommate or partner who had a contrary pet proclivity?
Interesting question. I like them both a lot. Cats *might* have a slight edge in general, but as a pet, if I could only have one, it might be a dog just for that loyalty factor. Which sounds odd, but there it is. It's also a bit odd for me to judge, since I've almost always had dogs (since I was like 4 or so), and wasn't allowed to have a cat until I was in... high school, I think? Maybe late middle school. Which kinda skews things slightly.
I wouldn't be able to live with a (permanent) roommate/partner that didn't want pets at all, probably. I could stand it if they didn't protest my having them, as long as they didn't have to love all over them.
