My cat has started digging loudly in his litter box every morning at about 4 am...he will dig in it FOREVER. He DIGS and DIGS and DIGS. Is it possible that something's wrong with him??
Get a deeper litter pan, and get him two litter pans. Use a big rubbermaid container and cut a hole in the side big enough for him to jump through but off the floor so the litter doesn't fall out.
LOL, my cats do that too. John and I have sat and listened to the obsurd amount of time that he scratches his litter around, lol. It just goes on and on and on. We're like, "OK, it's covered already!" LOL, i don't know why they do that, but if that's crazy, you should see my cats, lol. That's like the least crazy thing they do, lol.
