i don't consider myself either. i just like pets period. i've got two cats right now because, like you said, they are easy to take care of, and i don't want to confine a dog to my one bedroom apartment. cats just lay around bulking their entire lives with the exception of their crazy cat modes every few hours where they tear ass around the place chirping like birds with pupils the size of satellite dishes. when i'm married and have a house, i will definitely be hooking up a big, fat lab or golden retriever.
on a side note, probably the most hilarious thing about having a cat is when you completely catch them off guard and they get the crap scared out of them. they involuntarily jump straight up in the air and just kind of go...BOING. it only happens about once every six months, but when it does, it's funny shit.
