Why won't my cat eat and has brown saliva coming from its mouth?

Sounds like there is a very good chance Marley has some sort of oral infection or dental disease. I would schedule an appointment to have her mouth looked at some time soon. They will be able to determine if the problem can be resolved with steroids and antibiotics, or if teeth will need to be extracted. Hope this helps.

Without examining your cat or at least seeing some photos it is very difficult for me to comment. The best I can tell you is that he needs to see a vet so he can be examined in person. He may have a seriously infected tooth or even a tumor in his mouth cavity. Both things can cause the sign you describe. He cannot be left in this condition without eating and losing weight. It sounds like he is in pain so he needs to see a vet right away. I would not wait to get him examined. This is an emergency in my opinion.

This sounds very much like she may have a tooth problem or a mouth ulcer or an injury. Since she apparently is in pain when you try to touch her around the mouth, I suggest you take her to your veterinarian for a dental exam. She may need a tooth removed or be treated for an ulcer or have tartar removed.

There are some contagious viruses such as calicivirus that can cause ulcers in the mouth along with other upper respiratory signs such as sneezing and nasal discharge. It is also possible that both cats were exposed to a toxin or something caustic that injured their mouths if they go outdoors or have access to any chemicals. If their symptoms have been present for more than 24 hours I'd recommend taking them to an emergency veterinarian. They can examine both cat's mouths to look for problems and determine whether or not they may be dehydrated from not eating or drinking.

Thank you for submitting your question regarding Sam. I recommend that he sees an emergency veterinarian today. He needs to be examined. If there is a smell coming from his mouth, I worry that he has a wound. If he is painful, then he will not open his mouth. There are also other causes of not being able to use the mouth properly such as infectious and inflammatory conditions. The veterinarian will examine him and may recommend some testing. Based on these results, treatment can be started to help him feel better. I worry that he will become dehydrated from not eating and drinking properly. This may need to be addressed as well. I hope this information helps!

Your cat needs to see his veterinarian ASAP. It is possible that your cat has a tooth abscess, severe periodontal disease, something lodged inside the mouth, an injury, or an oral tumor. Regardless of cause, this is a serious medical condition since it is preventing him from eating and drinking normally. Your cat is at risk of becoming dehydrated and developing a condition called hepatic liposis, which can lead to liver failure. Even going 24 hours without food can cause changes in liver functioning.

It sounds like Archie may be sick. It sounds like he is lethargic and having a decrease in appetite, both of which are signs of illness. He could have a dental problem, systemic illness, infection, inflammation, or injury causing these symptoms. The drooling could be due to dental problems, pain, or nausea. I wold take him into a vet now to get checked out. I hope this helps!
