I was looking for something to put in front of the litter tray in the dining room. It has sanded and polished original floorboards so there are gaps where the litter falls through. I had one of those rubber things from PAH but they are a pain as the bits get stuck in them. I found a cheapo version of a turtle mat (machine washable with non-slip backing, except these are polyprop rather than cotton) for £4 but they also had some large cotton rugs reduced from £4 to £1 - they are 60 x 90cm so quite big. No idea how they could be used as rugs as they would slip around - but they are good for covering chairs, for kitties to lie on in garden, car boot liners etc etc. They only come in dark green.
