You know...sometimes a simple antihistamine can help in situations like this. They often have a slight sedative effect and if it is an allergy they may help in this regard also. Have you heard of Chlor-Trimaton. I think that is the correct spelling. I know if you take a 4 hour Chlor-Trimaton and give the cat 1/2 of that every 12 hours it is a safe dose. If you don't have the Chlor-Trimaton then I would ask the vet what another safe antihistamine would be. It would be inexpesive and worth I try perhaps??
