Hello! My cat Daisy (3y/o F, spayed) has been having upper respiratory symptoms, specifically, nasal discharge in one nostril, reverse sneezing, and congestion on and off since November 2024. She is otherwise acting normal (same appetite, energy levels, etc). She will go a day with these symptoms and the next day they’ll clear up, then come back again. I’ve taken her to the vet twice and the first time they said to just give lysine supplements (didn’t work) because she’s had a history of URI when I adopted her 2 years ago and the second time they said to give chlorpheniramine (which didn’t work) and then prescribed hydroxyzine (which also didn’t work). I don’t really know where to go from here if it isn’t allergies. Just wondering if you have any thoughts? Thank you!
