Confession time! I'm a HUGE cat person. Dogs get the credit for this, but cats are just as loyal and playful as dogs.
I am a dog person so you have to convince me about cats ;)
Well to start, how often do any dogs you know hunt mice or other "vermin" around your house?  I know the corgi I used to have wouldn't.  All she was good for was sass.
I do admit I like that domestic cats still have their wild instinct in them and dogs are become less of a "wolf"
I just appreciate cat behaviors in general, from their body language, to their playing styles, and their urine marking.  Actually, forget what I said about their urine marking.  That's no fun at all.
