Ness (my ham, not the OP
) is a terrible bar chewer. I tried to stop this by putting her in a Zoozone, she really didn't like it and was frantic, chewing the spout of her water bottle, and when that was replaced with a bowl obsessively trying to reach the roof bars to chew, which she'd manage and then be hanging off there. Tried her in a Gabber to see if she'd be more relaxed as the base isn't so high so she could see out better, thinking that might be the problem. She just didn't settle, and began to chew the plastic
so it was clear that she was unhappy in enclosed cages and I switched her back to her barred cage where she is much happier. Strangely, now she's back in there she seems to do it less (although sadly it hasn't stopped all together). It's like an obsessive thing with her. However I've been trying her with much deeper substrate so she can dig and that seems to have had an effect
