Have an 8 year old cat. Has had sneezing spells on and off for several years.
Now has ONE nostril swollen -other is normal, and raw/red with some pus and small 1mm sore which opens periodically-this is more recent, over last few months.
Continual nasal discharge serous, sneeze is serous
Shaking his head peridodically.
Appetite is suppressed.
When stressed a few months ago, he developed mild conjunctivitis which cleared up on saline irrigation.
He has a broken molar and most of his teeth are gone, gums are reddened, but no obvious abcess/swelling.
Have tried these so far:
Tetracycline for about a month. Intialing sneezing disappeared completely, but came back towards
end of treatment. No effect on sore nose or swelling.
Lysine 500mg bid
Topical terramycin ointment on nose, -no effect
Has broken tooth, and very few teeth left, reddened gums, stinky breath which clears on antibiotic treatment.
Started on cephalexin. Nose swelling has diminished, but not disappeared. Sneezing stopped for first day or two, then returned at lesser rate
Nose is bothering him, he ocassionally paws at it aggressively.
Redness has diminished so far on the cephalexin.
Last vet thought it was herpesvirus and secondary infection but was guessing, since no tests were done to confirm this.
What is causing the one nostril swelling, redness and sore? Why won't it heal?
If the sneezing is due to secondary infection, why does it dissappear then reappear on antbiotics?
What is needed to DEFINITIVELY determine what is causing this cats upper respiratory congestion, nose swelling/sore?
Thanks for any GOOD answers.
