I have two "kitty kups" that I got out of a catalogue many years ago. They're plush, bowl-shaped beds. All of my cats that I have had since having the kups have slept in them, at least from time to time. But there have always been the ones that just love them - of the two tuxes and two stripes I have now, the two stripes are always in them, sometimes both of them in one. They like them so well, they have been known to curl up in them even when I have them in odd places - like on the coffee table when I'm picking up to get ready to vacuum! My son was kicking around the room once (practicing his hand stands! ) and knocked one of them into the other. A while later there was Pepper, sound to sleep on top of the "stack"! They'll sleep in them when they get knocked over on their sides (kinda like sleeping in a tent!) and have even been known to sleep on top of them when they are completely upside down! They just love those kups!
