One of the feral cats I feed showed up today with his left cheek very swollen. He seems to be eating fine but also lethargic, I don't have a trap to catch him and really have no clue what is wrong. I've read it could be a tooth or an insect bite. He is not a cat you can touch but he is letting me closer to him than usual.......any ideas would be greatly appreciated! P.S. I haven't been able to get in contact with any cat rescues in this area 07726
