Today, my little brother found our chinchilla hanging half in, half out of his cage. It was a VERY tight fit. I don't know how long he was there (it was morning). We got him out of there right away, but he's weak and really doesn't do much. We're thinking he cut off the circulation in his back legs. We think We put him on a heating pad and tried to give him water. We're afraid he might die. Please help!!!
