I have a domesticated squirrel. I think he is a well adjusted and happy animal. My concern is probably a common one for someone with an indoor pet squirrel. I'm concerned about his teeth getting too long. I give him lava blocks and elk antlers to chew on but I think his teeth may still be getting too long. Can anyone give me some advice about this? I'm wondering if there is anything I can give him or do for him to trim his teeth down?
