Hi guys I got a guinea pig 3 month ago and a couple weeks ago he started chewing on the cage bars at night at the SAME TIME every day. I tried giving him more veggies and hay before I go to sleep and that helped couple of times but he hasnt completely stopped chewing the bars. One night I removed the cage and he got out and walked around for a while and then went inside and was quiet. I let him out of his cage everyday and he never wants to come out this bad during the day. The chewing lasts for around 10-15 mins max and then he gives up and goes to sleep. I dont know what to do because I think that if I give him any attention when he does it he will never stop but I'm worried about his teeth and that they might break. Pls help me
