My poor old hamster died 2 weeks ago,he was nearly 3 and we got him when he was about 6months old. I bought another hamster last week and he's only 7 weeks old and he chews everything, pillows, towels, clothes etc. Is there something I can give him to chew other than wooden toys when he comes out to play? My other hamster wasn't like this but I don't know if it was because he was older or that he just didn't chew everything in sight.Will he grow out of it?
