About the only time I've witnessed a cat actually using a pet bed is when they were stealing it from a dog. : ) They really seem to prefer boxes to just about any other type of bed.
The "kicky toy" mentioned by Trudii is a real fave in our house (6 cats). I use upholstery weight fabric for extra wear and tear as one of our cats likes to chew holes in fabric (no, I don't keep a quilt on my bed, why do you ask? Ha!).
All of mine do like the cat mats (basically place mats with a bit of cat nip in the batting).
