I came home this morning from work and my poor chin is limping. I have no idea what happened!!!! She's usually so active and full of energy but now she's limping. I cannot tell if it is the front or back paw and there is no swelling or dragging going on. I have all wooden shelves in the cage and no metal wiring too. I physically cannot take her to a vet anytime soon. The roads are solid ice here and it took me three hours to get home when I usually get home in 15 minutes! I almost didn't make it home this morning! The weather is so bad here. Any suggestions? What should I do in the meantime?
