Cats and dogs all have different personalities. I've known cats that act bouncy and crave attention, who want to be inside, who wants to be outside, those who want both all the time and at the same time. I've also known smelly dirty cats who do not care where they go to the toilet or vomit. And I've known dogs who are like big lazy lions, and also neurotic little demons, some who are fastidious about their hygiene and others who get so excited they can't hold their bladder.

I like both, and I'd have either, but I like a cat or dog who is clean, chill, intelligent and likes adventures as well as napping. Bonus if they don't like other people much. Greyhounds are the fastest couch potatoes out there.
