Hi all, thanks for your replies. We've put a sandpit because there's a patch of soil within his enclosure and he was digging that up, so we thought we'll put in a sandpit for him. He seems to like it, he still digs up all the treats and toys that we hide in it, but the thing is he is weeing there. I'm sure it's not a cat because I saw him do it once when I came home early from work
