My 7 year old male long haired cat began 1 week ago with a honking sound and increased grooming. I brought him to regular vet for exam and they suggested upper respiratory infection, despite no fever/discharge and gave convenia. After 2 days snorting sound is worsening and he was making frequent trips (6/hr) to litter box to urinate without production of urine. I brought him to emergency vet, vitals are normal, bladder was empty, it was suggested cystitis from stress, and sound may be possible naso -pharyngeal polyp, nsaid provided. He has been on nsaid for 3 days, honking sounds have gotten worse and now has whistling sound through nose with breathing. I consulted with Dr Hahn office: east end veterinary hospital in Riverhead and they quoted me $6,000 for CT and scope to diagnose whether polyp or inhaled foreign body in nasal passage without guarantee. My cat is currently eating, drinking and producing urine and bowel movements but honking sounds when grooming, eating food and playing with toys. Over the last 24 hours he has begun frequently scratching his right ear. I have already been to my primary vet and emergency care and invested almost $1k and still don’t have a definitive diagnosis. I watched Dr Krista Magnifico video on YouTube and was wondering if you have a recommendation for treatment or evaluation here on Long Island that is more reasonable? Would nasal foreign body cause similar honking sound to polyp? In your opinion what is the best way to move forward with treatment?
