WHat are treatment options for a 3 year old cat with chronic sinusitus. Symptoms dissappear when treated with injectible baytril and reappear approximately 1 week after treatment has ended. He has tested negative for fe-leuk and FIV multiple times and is strictly an indoor cat.
The infection should be cultured to find out the best antibiotic for your pet. The antibiotic therapy should be long term. Skull exrays should also be done to rule out a mass such as a polyp. This can cause a chronic infection. Good luck, vetadmin
