My outside buns have a high sided corner one with a little entrance, and Nigel shares the tray with the cat. I tried the compressed wood litter but it breaks up and gets messy, so now we have the white hygeine litter (not the dusty clay stuff)
I had read that some rabbits eat it but he went there from choice and never seems the slightest bit interested in nibbling it - maybe because it has cat wee on it!
Apart from a few raisons he leaves by his food dish (but only at night?) he uses the tray without missing. It's the cat who needs better aim! :lol:
