A few days after bringing home our two kittens, we took them to a vet to see about having them treated for ear mites since they were continually scratching their ears. The vet cleaned them out and applied a treatment for infections, and told us to bring them back if they continued to scratch. It's now been three weeks and they are still scratching, so we brought them back today. The vet cleaned out their ears again with something that he said was for mites, and sold us a little bottle of Otiflex C, which is supposed to be an antibiotic, anti-fungal, and anti-inflammatory. They also gave us some Enroxin tablets, which turn out to be another antibiotic. We were told to bring them back in two weeks for a check up, and that they couldn't give them Revolution because of the flea treatment we gave them three weeks ago. Is this a normal way to treat itchy ears?
