I like cats, more so than dogs for a house pet.
They seem to be a bit cleaner than dogs do, so long as keep the litter box clean
(Well, most cats)
Most dogs like/get along with just about everyone.
Cats on the other hand ... its alot harder to get one to show affection.
They like thier "Me" time which is fine by me. Im the same way, so for me, a cat is the perfect house pet.
