We currently use the pellet litter that looks like its made from recycled newspapers or something, the cats are happy using it but as it is non clumping, its pretty hard to remove wet stuff from the tray without having to totally change the litter, which would work out very expensive. If there is more than one wee in there, chilli won't use it for pooing in and goes on the mat next to the tray. It also doesn't cover smells well.
I'd like to change to something clumping, but it would have to be fairly large grains as the little box is on carpet, it has a mat under it but most of the grains would end up on the carpet! Anyone have any recommendations?
