my cat used to do this. I think it’s less wall-scratching and more his trying to get his paws clean. If you have clumping or perfumed litter it may be irritating his beans. You might try switching litters or putting a bit of rug on the wall. switching my old boy to a non scented corn-based litter stopped this habit, ymmv
Shh if the guy you’re replying to could read history theyd be very upset
Did the probe share parts etc with the eagle talon and the Mitsubishi eclipse or am i thinking of something else?
They’re hoarding all the wealth and are a rich source of vitamins and minerals
