Why is my cat drooling, eating less, less active, and has bad breath?

Hi. It sounds like Oliver has some severe dental disease. He most likely has gingivitis and possibly a painful, loose, or resorptive lesions on some teeth. Dental disease in cats can cause pain and discomfort.  This could impact quality of life. In some cases, the dental disease can cause a cat to stop eating. For dental disease, besides brushing teeth with pet toothpaste daily,  your veterinarian will recommend removing plaque and mineral buildup by scaling and polishing the teeth. Teeth will try to be saved wherever possible. In extreme cases, extraction of teeth might be needed.  Unfortunately a veterinarian will need to be involved.

It's hard to say what could be causing this. Possible reasons include oral pain, something stuck in the mouth or throat, periodontal disease, oral mass, viral infection, among other things. You can try liquid foods, baby food, or even putting canned cat food in a blender to make a liquid.

Typically excess salivation is either caused by nausea or pain (oral or abdominal), although this is not an all inclusive list. There can still be oral disease present, especially if these missing teeth were not removed but fell out. Cats can get resorptive lesions of their teeth which can be really painful and the changes can be hard for owners to detect. They can also get lesions in their mouth (stomatitis, a mass, ulcers, etc.) that an owner may not see. Additionally diseases of other body systems may cause drooling (kidneys, gi, etc ). I would recommend your kitty seeing a vet for a thourough oral exam and blood work to start. A good oral exam will likely require sedation and perhaps dental xrays. Additional testing may be recommended based on the case. I hope this helps and thank you for using Petco Pet Education Center, formerly Petcoach!

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Poor Castiel! I wonder how old Castiel is? Causes for drooling and a decreased appetite can be from dental disease/rotten tooth, ulcers in the mouth from a virus or licking something caustic, kidney disease/other metabolic conditions that cause nausea or a foreign body in the mouth. I think it is best to have your Vet examine Castiel and take a good look in his mouth. I hope this helps and I wish you all the very best!

I would be concerned she may have kidney disease - reduced appetite, tooth loosening and vision loss due to high blood pressure and retinal detachment are common side effects. I recommend a vet check as soon as possible, taking a urine sample using special collection litter would be helpful for full assessment

Poor Snuggles! Drooling can be a sign of pain, nausea, getting into something toxic, and dental problems in cats. Given that she doesn't want to move and is making weird noises, I would be concerned that she is in pain and may have been injured during the day. It would be best if she was seen by a vet right away for a health check.

Even with no teeth the drooling is abnormal. I would be concerned that he has an infection or stomatitis of the mouth or possibly kidney disease causing him to be uremic- a build up of toxins in the blood that can cause ulcers and other problems. I would recommend getting him to a vet for evaluation and possible medications to help keep his twilight years comfortable.
