The thing I found when I had Max was he loved boxes, so I would hide toys in them and change his toys around. Plus I found sometimes he did some things to get a reaction out of me. Like when he climbed the curtains. I just started ignoring him when he was up them and slowly he got bored, especially as I would give him a bigger reaction when he came down.

Now though, he lives with my mum after she kidnapped him. (I moved back in with my mum for a time and she got attached to him, and he's gotten attached to beating up two dogs and has his new buddy, Polly, after my nan died. Who are now beating each other, after Polly's teeth were sorted the other month). Now Max has his buddy though, I've been hearing he's getting into load of trouble with Polly.

This might sound daft, as he loves the plug so much, (I'm guessing its the plug), why not give him that one and get a new one? Then he might not be stealing yours.
