My Mitzi is a litter-flinger too Her box has a lip around it which seems to keep most of the litter in the box. Mishi, however, doesn't like to get his paws dirty and seems to think that pawing at the rug around the box will do the trick. My Goldie used to do that too; she never did figure out how to bury her "stuff." I'm hoping Mitzi will teach him some of her "digging to China" tricks, without the litter-flinging part.
