Which are best?

Cats:
1.- They're nice to you before you feed them.
2.- You just leave them alone and they take care of themselves.
3.- They're clean, look cute, do cute things.

Dogs:
1.- They're nice to you all the time.
2.- Require a fair amount of interaction, specially if you live in a city.
3.- They smell... they all have that dog smell.

If I lived outside a city, a dog would be the go. In a city cats rule.
