Thank you for submitting your question regarding Rocco. Excessive drooling can be the result of nausea, mouth pain or a bad taste in the mouth. I will typically treat with anti-nausea medication to see if it helps. If not, make sure that he is not eating anything that he shouldn't (plants, etc). Finally, I will anesthetize the patient for a thorough oral exam, dental radiographs and clean the teeth. I hope this information helps!

    I'm sorry Jinxy isn't doing well! This excessive drooling could be due to a dental problem such as a tooth root abscess, severe gingivitis, or a broken tooth. Pain from one of those conditions can caused him to be usually quiet. He could also be nauseous causing the drooling. I would have him seen by a vet for this excessive drooling. The vet can diagnose what is causing it and can prescribe a treatment for it. If he does have a dental problem, he will benefit from a dental cleaning, scaling, and polishing.

My cat seems to be salivating a lot but does seem to still have an appetite. As far as I can tell he has not gotton into anything. He had a little poop om his butt stuck to fur. What could this be?
Salivating is a sign of either ulcers, or bad teeth, excessive tartar, abscesses, or an injury in the mouth or an irritant. I suggest you take your kitty to a veterinarian tomorrow morning for an exam. He also may have a nasty calicivirus infection. If he lets you, you can try and have a thorough look in his mouth, but it is more likely that his mouth is painful. Make sure he eats and drinks, preferably give him some canned food as it may be less painful to eat.

Peanut has viscous foul saliva. No apparent oral issues other than missing teeth. She is approx 14. For past 3 months eats wet, grain free food and eats well. Is alert and active. Prior to this was eating dry food, losing weight and hair was dull wit
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 Boop by Petco!

Excessive drooling,my cat have been experiencing,what should be the home remedies for this?
Excessive drooling in a cat is almost always from some type of issues inside the mouth - like he tasted something (like maybe a plant) that didn't taste good or there is a problem with a tooth (broken or infected). Other options: nausea, ulceration in the mouth and kidney disease. The best I can tell you to do at home is rinse the mouth with plain tap water. You can him some human antacid medication but I don't know what you have available to you so if you would like to see what products you have and post again we can help you with how much to give him.

Pou started drooling off and on starting Friday. He growls at his brother and sister and sleeping a bit more. I checked his mouth everything looked normal breath doesnt smell and i dont believe he has a fever he is moving around fine and doesnt seem
Thank you for submitting your question regarding Pou. Drooling is typically the result of nausea, oral pain or ingesting something with a bad taste. He will need to see his veterinarian if his symptoms persist. If he did acquire the respiratory infection from his housemate, then post-nasal drop could be making him nauseous. I hope this information helps!

Hi, about an hour ago Rocco started drooling excessively. He didn't get into anything and he isn't anxious or stressed. Besides the drooling, he's acting completely normal. I checked inside his mouth and his teeth look okay. About 3 weeks ago he got
Although the area in your picture does look red and potentially inflamed I don't think it looks infected. It would be best for your vet to make that call in person - I'd recommend making an appointment to have them examine the area in person and until then you should prevent Rocco from licking the area. I doubt the drooling is related. Drooling can be related to a tooth problem (possibly something you can't see), nausea, pain or ingesting something that tastes bad. If the drooling continues you should bring this up to your vet as well.

Hi, my cat is a really friendly one, Leo likes to play with us and other cats I have in my house.. but recently(in the past 2 weeks), he’s been drooling all over himself and since then he never sits among us or other cats, he’s usually really active
Drooling can be a sign of dental disease, oral ulcers from ingesting toxins or from some medical conditions, or even nausea or pain. If you feel Leo's behavior is abnormal you should either recheck with your vet or get a second opinion elsewhere. A sedated oral exam might be helpful, or blood work might be recommended as well.

My cat is a 3 year old male. He has been uncontrollably drooling for at least half a day. I do not know why either. He seems a little more unmotivated also.
Poor Fiefie! It sounds like something is definitely wrong. Excessive drooling can be a sign of nausea in cats, or can be caused by a problem in the mouth such as severe dental disease, a foreign body, or even an oral tumor of some kind. If he will let you, you can try gently opening his mouth to see if you can see any obvious problems inside. If not, I would recommend taking him to the vet today for an exam - he/she can sedate him if necessary to perform a more thorough oral exam, and may also recommend blood work or other testing if needed to help diagnose the problem.

Cat started drooling excessively. When I opened his mouth It looks like his gums are irritated around his teeth, especially on the left side of his mouth. Should I take him to the vet or get a teeth cleaning, or brush his teeth at home? Or could it b
Thank you for submitting your question regarding Cheech. I recommend that he sees his veterinarian. From your pictures, he appears to have significant gingivitis. This will make tooth brushing painful for him. He will likely need to go under anesthesia for a dental cleaning. Drooling most commonly results from oral pain or nausea. I hope this information helps!

Why does my cat drool so much when I pet him? He drips and has a stream of slober down his face..
Excessive salivation could be caused by a number of things, including nausea, dental pain, toxin ingestion, a foreign body stuck in the mouth, injury to the tongue (as can happen with electrical injury from chewing on electrical cords). Please have Sylvester seen by a veterinarian as soon as possible to help rule out a medical cause for his behaviour, and for treatment if necessary. If Sylvester could have eaten anything such as medications, household cleaners, plants, toys, food scraps, or garbage, please let the vet know about it to help them determine if there could be toxicity. If medical causes are ruled out, then the drooling could be just his reaction to being pet. Some pets will drool when they are happy or relaxed, which may be what is happening with Sylvester.
