My F2 Savannah kitten has something terribly wrong. Before I got him from beeeder they said he got into something and was itching his ears they gave him Benadryl and was doing better. We got him and about 3 weeks later the symptoms started again but worse. This time aggressively itching to the point of bleeding. Face swelling ,coughing, sneezing, runny nose, both eyes swollen. First vet said allergy and gave clavamox and steroi. Kind of cleared up then came back again for the worst. Took him to a different vet and they said staph infection and gave onsior and cefpodoxime. Well since giving that it’s gotten even worse. Too him to another vet this morning and they are wanting to do other test; upper respiratory panel, feline serology 1 and 2, I am starting to think that I got 2 unhealthy cats from Exotico Savannah’s. Both of my cats have so many problems. Help! Are these the right tests? Anything I should tell the vet to look for?
