Being in a rented house sucks
Have you tried carpet tiles the the places he does it, before he does damage?
What about some rugs? you can get some great ones in ikea, that might work??
Its covered by a rug already, he's moved it out the way to do the destruction
Sorry, this all must seem really negative of me just saying "done that" etc, but it really is the case. I hate having to restrict them, but i can't do anything else now
