Please Help! When I checked on my boys yesterday, I noticed Lestat, my dumbo rat was not putting any weight on one of his back legs and his foot looked a little swollen. When I checked on him today there was no improvement. He is in a cage with a reg. fancy rat, they are both about the same size. I am really worried about him. Is there anything I can do for him, here at home before taking him to a vet. Any suggestions would be appreciated. Thanks.
