My 14 week old kitten has no trouble using the tray to do his mess in, but he also plays in it!! He tries to 'bury' the dirt which I understand, although he get a bit excited and ends up flicking half of it on the floor! I can see he enjoys it, and is having fun. But it means constant scrubbing of the floor, and giving him frequent baths as he gets covered in the nastiness! My two year old cat never did this, he just does his business and leaves it! Has anyone any idea why he does this, or how to stop him?? Thanks in advance!
