Hi there i am housesitting a friends house along with her cat over the past day ive noticed she is not eating or drinking and her tongue is alil out of her mouth but not all the way out it also sounds like she has a blocked nose im really worried is this just a cat flu or should i take her to the vet asap
yes, please get her to the vet right away. it sounds like she could have a very bad upper respiratory infection which needs antibiotics quickly. the longer she goes without food the more danger of getting fatty liver disease which can be fatal.
have you taken her to the vet? how is she now?
