Mark, did you notice if they have any of the enclosed/covered up litter trays, whatever you want to call them? I think I need to invest in one as Bonnie thinks she is digging down to Australia. I use the wood based litter as I think it's better than others but my house is sarting to look like a ruddy circus ring with the little darling!! Thanks.Mary
Still think the wire top-opening ones are best though (heavy though!)
