My ferret was hanging by the neck from his hammock, we cut him down and stuffing around his neck was very tight so we had to cut it again. Now he is having a hard time swallowing food, We gave him apple sauce and he kept on trying to eat it and then minutes later he spit it back up. I think this is due to his throat being swollen.Is there anything I can do besides just keep on trying to feed him liquids? Also I put ice on his neck to try to help. Also not willing to spend a lot of money on a vet since he is very old.
