Thread: Dirty Rear End?

I've not had experience of that little problem so far, but one thing you said made me wonder if the vet's got a good point... I'm assuming the litter tray you use for the older cats has shallower sides if it's smaller? Perhaps you should try a bigger tray but with shallow sides? It makes me wonder if she has trouble getting over the top of the bigger one. Just a thought. Hope you find a solution though, it's so undignified (for the cats) to be cleaning their behinds. I'm fortunate and only get the problem if they've eaten something that's given them Runny Bum Syndrome.
