I got a barn kitten that someone didn't want, she's is now 9 yrs. old, she's a housecat. always sneezed a green or yellow discharge & sometime a brownish-red watery discharge is in the inside corner of one eye, I tried baby nose drops for a while & then tried saline neither worked, its nothing catching because the other cat never got it, she eats alot but has always stayed thin. help!
Maybe your pet has feline leukemia or feline aids. Both supress the immune system and can cause what you are seeing. It could also be a chronic herpes infection. This is viral a difficult to cure. It sounds like your pet needs an antibiotic. Good luck, vetcare
