I have a 1 year old cat. She has been drooling for a month now. Vet says she is having somekind of infection and even after few course of antibiotics her dooling didnt stop. He also said that maybe she is allegergic to the food you give to her, but I mostly give her boiled chicken and sometime canned cat food. When she is on antibiotics course she show some kind of recovery then her condition becomes just like before, her tongue sticks out and she keeps on drooling. I also noticed that she has some hard time swallowing food. Her heart is always beating very fast, when i asked about this from vet he said that she is going through heat cycle thats why, but i doubt that. Another thing kind of unusal is blood on her teeths. I think she has stomatitis, but her gums seems perfectly alright and no signs of bad breath, the problem is just their are red marks on her teeth
