My hamster is about a year old now and was healthy when I got him. I think he is sick though because of the way he looks and acts, he also looks lathargic. I had him in his playpen the other day and I laid out some towels under him because he digs in his food and I didn't want him to make a mess on the floor. Well I went to clean his cage while he was in the playpen and I guess I must have had him in there to long because when I came back he was trying to escape by chewing on the towels. Im worried that he might have eating some of the towel and now it is in his body but I'm not sure. He acts mostly like himself but sometimes when I try to pick him up he moves away and tries to hide so I won't pick him up. Could there be any other reason that he looks sick?
