If you are looking for something special for your cat try a Boogie Mat. I recently purchased one at a cat show for £7.99 and my four Ragdolls were queuing up to go on it! Basically it is just a zipped flat cushion about 14 inches x 12 inches with a bit of padding and you sprinkle cat nip inside it.
If you are not a frequenter of cat shows then I think you can get one from
www.madcats.co.uk or Purrsonal Touch (sorry don't know their website address).
