Cats have such wide, varying personalities, it's just like dogs... just less stupid. I have a couple dogs too, but cats are more fun. One of our cats even tries to play catch with the dog (beats her to the object and pounces it) but apparently doesn't understand the whole retrieve thing.

My personal cat that is getting up there in age sleeps with me every night. She waits for me on my bed at night and when I get in the bed, she crawls on top of me.
