Cheech is awful for it. I let her pick her own treat from the box and she shoved her head in there and took about three. So I closed the tub and she got in a mood with me, hopped on my shoulder and started chewing on the wall. When she's out she'll go behind the curtains, under the bed, anywhere where she knows it'll take me a little longer to get to her and chew, chew, chew. And she eats it! She knows she's not allowed, because all I have to say is 'oi' and she'll scurry off to do it somewhere else. She's driving me mad. That and pulling out chunks of the carpet and eating that. And she'll run around the room with bits in her mouth until she finds a safe place to eat it.
I love her!
I saw someone who had very cleverly put metal guards on top of all their skiring boards (do you call them base boards across the pond?) and along all the corners of their walls but mine are taking chunks right out of the middle of the walls...
