I've always had cats, so I guess a cat person. I love dogs too though, the bigger the better. But I don't have a house or yard big enough for a dog, nor do I have the time.
Although for a couple of years I lived without pets, and I have to admit I liked it better. My parents recently moved cross country so they left our old cat with us. I love him with all my heart, but our Nick is an absolute asshole.
4am wake up calls daily. If we close the bedroom door, he will scratch at it and yowl until he throws up. He throws up for attention, and he will always make sure he throws up on shoes if he can, or a rug if not, even when there's linoleum or wood right under his feet, he will walk to shoes or a rug holding in the vomit until he reaches them.
I miss sleeping the whole night through. I miss not worrying about him constantly, as he's 16 and has medical problems. I miss my house not smelling like a litter box, even though I clean it constantly.
