We were just given a 7 or 8 year old chinchilla. He doesn't look like he was well taken care of. Big patches of fur are gone. He didn't have a good home. He was kept outside in a garage with very little play things and the bottom of the cage was all wire. I need help on whats best for us to help him get well. He is curious and friendly. He's not super skittish, but he does seem a little unhealthy. His cage was covered in weevil bugs and had spiders/spiderwebs. We would like to eventually move him in with our other male chinchilla, but I want to make sure he is completely healthy.
