I have an 11-year old female domestic shorthair cat (Nala) who has been very healthy until around springtime last year when she started to develop a snorty sound when breathing and rapid sneezing fits. We figured it was maybe allergies at the time, as ours were really bad too. But it kept lingering and we finally asked our vet and he was reluctant to do a full exam on her because of the expense, and he also diagnosed her as having herpes, and prescribed Chlorpheniramine 4mg and Duralactin paste 2.5ml for her. I give her a 1/4 of the pill crushed in her canned food once a day, but the paste makes her sick. I have been giving her the pill for about 3 months now with zero improvement. I have been doing a lot of research, and the closest thing I could find that matches what she is dealing with is a video I found of Dr. Magnifico performing surgery on a cat for a nasal polyp. The description she gave completely matches what Nala sounds like with the snoring sounds when breathing and the constant sounds of trying to clear her throat. She has lost a lot of weight because I think it’s difficult for her to eat a lot but otherwise she acts like nothing is wrong, she is very playful, and also eats (best she can) and drinks normally, and litterbox habits are still great. My question is if this diagnosis sound like it could be correct, and if so, is this something that could possibly be fixed without breaking budget?
