Mat for a cat

I had to buy a new mat today, the old one was worn out. The cats love it, they have burrowed underneath it, scratched their claws on it, played with a tiny toy and a ball, (both under the sofa now). The mat is where we walk by the sofa and one of the cats has decided he wants to sleep on it, but as I’m walking backwards and forwards over it he’s had to move. No doubt he will sleep there tonight! The cat will be sleeping on the mat. X
