A cat’s mouth – and a human’s – is constantly producing saliva to prevent dryness as well as moisten food. Saliva also contains an antibacterial agent that helps keep kitty clean and heals wounds faster. Even perfectly healthy senior cats commonly drool, and some felines are dribblers from birth. “It seems that a small but significant percentage of cats drool in response to positive stimulation, which is typically also accompanied by purring, rolling over submissively or rubbing their faces against the objects of their adoration,” says Dr. Patty Khuly. “Most of these cats will be lifelong ‘happy droolers.'”
However, there are serious health conditions that may result in your cat drooling:
- Ptaylism, also known as hypersalivation, can be caused by neurological dysfunction.
- Motion sickness in cats involves the nervous system as well; cats traveling by car commonly drool, sedated or not.
- Diseases like rabies, encephalopathy, and brain cancer also list drooling as a symptom, while injury to facial or esophageal nerves may be the culprit.
- If the salivary glands are impacted by tumors, inflammation or trauma, it can also result in a cat drooling.
- Poor dental health is usually the reason for a drooling cat; periodontal disease, like gingivitis, or an abscessed tooth cause considerable pain and hypersalivation to pets.
- Accidental poisoning in cats is the second most common cause, whether the toxin is a household chemical, human food, venomous creature, or plant.
Many medical conditions have similar symptoms and are easily confused, making a veterinarian’s professional diagnosis necessary. If you suspect your pet is ill or injured, you can always call a local vet clinic and explain the situation; most are more than happy to advise you of the situation’s seriousness.
If the drooling is caused by an underlying condition, typically other symptoms will be present. Cats with dental trauma or disease may also have bad breath, swollen gums, and loss of appetite. Tumors often present with varied symptoms depending on their location, but sudden weight loss, visible lumps, or excessive meowing due to pain are general signs of cancer in cats.
If your pet has been poisoned – depending on the substance – it should be treated as a medical emergency! Vomiting and diarrhea may occur, Common cat poisons include lilies, antifreeze, marijuana, raisins, and alcohol. Many human foods and indoor plants aren’t safe for felines, so always consult your vet or the Pet Poison Hotline‘s handy guide.
Depending on the root of your cat’s drooling, treatment could be as simple as a tooth extraction or as complex as surgery and chemotherapy for cancerous tumors. Often a dental cleaning is needed to remove the buildup of plaque and tartar on a pet’s teeth, a pricey procedure that requires anesthesia and is excluded from most pet insurance coverage.
Emergency treatment for a poisoned pet involves purging the toxin from their system, typically through a combination of induced vomiting, charcoal, or intravenous fluids. Lilies, for example, are extremely harmful to a cat’s kidneys; a constant IV drip is necessary to flush out the toxin, while overnight monitoring ensures the danger has passed. This rehydration is also essential for pets who have vomited or suffered from diarrhea. If you call a pet poison hotline or emergency vet clinic, they may advise you to feed your cat activated charcoal, which absorbs any of the substance still left in the stomach.
Brushing your cat’s teeth can prevent plaque and tartar from attracting bacteria, which leads to painful gum inflammation. Abscessed teeth can also result from a combination of too many treats and too little brushing. Try a fish- or chicken-flavored toothpaste, along with a small fingertip toothbrush for cats! Start by acclimating your pet to being held for a period of time and then to having the brush rubbed across their gums. For cats averse to toothbrushing, ask your vet about a fluoride solution that can be added to a pet fountain to keep teeth squeaky clean.
If your cat has been given a clean bill of health but is still drooling, your only solution may be a good ol’ fashioned towel on the lap. Eating may be difficult for cats suffering from periodontal disease, so consult your vet to see if special food or nutritional supplements are needed. Wet food is often easier for toothless or elderly cats, as it requires less saliva to moisten and eat.
Like anything and everything to do with felines, determining why a cat is drooling can be a complicated process. There are many illnesses and injuries that can cause a cat to drool, so it’s best to consult a veterinarian for a definitive diagnosis. Sometimes the behavior may be entirely benign, but better safe than sorry! Adult cats should visit the vet once yearly, a senior cat biannually, and kittens according to their vaccination schedule. Paying attention to your pet for any sudden changes in behavior, like drooling, is important because you may catch something serious early.
