One of my two Guinea pigs has taken to chewing his cage bars in the early hours. I totally understand why he does it but it is waking me a night as his cage is under my window. I was thinking of trying to attach some wood to where he chews as he likes to chew the wood of his hutch too. Is there any wood I should avoid? Any other tips? His brother is in a cage underneath him and he doesn't do it but he isn't as much of a chewer as Ted
