To a cat every mouse is "his mouse"...or "hers", as the case may be. Every chair and cushion likewise. Also every sunbeam.

There was a cat which used to come and clean itself, yawn, stretch, and roll around sensuously outside the picture window of my aunt's house...while inside the family weimeraner (a born cat hater) stood frozen at the glass, trembling all over and moaning, as well as drooling copiously on the carpet and the window. That cat knew exactly what it was doing. It would torture the dog for periods of up to 1/2 hour before sauntering off in a leisurely fashion.

Like Sharon said: Cats rule, dogs drool.
