Edgar digs in his litter too. But usually only when its new. I was using Johnny Cat, but he seemed to use that less and less. I guess he hated the moisture activated perfume or something. Then I tried EverClean heavy duty clumping litter. After I finally got all of the *cement* off of his face and fur, I am now trying Cat Country natural pellet litter. He started doing the backstroke in it even though it was kinda dirty at one end, meaning that maybe the oder control in this stuff works *too* well. Anyhow, 'bout that time (yesterday) I took him into the vet for #3 canine distemper and rabies vaccines--never any reaction. Vet pointed out that he was cryptorchid (only one testicle descended) and that this may be the cause of his erratic preeing and such. He also mentioned that cryptorchids have been known to behave *very* strangely, and that it was best to go ahead and neuter him, which I had planned to do anyway. I had figured that the other would drop when it was good and ready, but apparently it might never have. So, now he's back, minus some fur and flesh, and is 3 for 3 in the litter box--yeah! I'll wait to see how he is when he gets his energy and strenth back...wish me luck.....Nevermind, now he's playing in it...(insert passage of time here) ah, now I see....everytime he starts to actually dig, grab out and smack him on the head. Wait until he actually starts to dig, so he doesn't think he's being punished for being in the litter box. I just hover over him as he's got his front paws in the litter and wait for him to dig, when he does, pow! Negative Reinforcement. Seems to be working great. [Posted in FML issue 1303]
