Why is my cat sneezing, lethargic, squinting, and not eating well?
Hello. You are describing Heidi with an upper respiratory infection. Most of these are viruses & generally run their course in 10-14 days. As long as Heidi is eating & drinking, she may not need to be on any medications. If you have never had her tested for feline leukemia & feline immunodeficiency virus ( & never vaccinated ), this might be something to request that your vet do this. This might change how she is or is not treated now & in the future. Just like with us, keeping her hydrated & eating are the best ways to deal with these infections. Offer her canned foods, broths or stocks & even tuna water. The more hydrated she is, the better she will feel. Any concerns, please see your veterinarian for further treatments. Thanks for using Petco Pet Education Center, formerly Petcoach.
