Ptyalism or sialorrhea is uncommon in cats and usually associated with particular stimuli such as excitement, hot or humid climate, and even the mere smell of food. When the hypersalivation persists for a while there is a high risk of it being associated with a health problem or injury.

  • dental x-rays to identify if the drooling was due to dental disease 
  • a biopsy in the case of a mass or oral lesion 
  • a complete blood count or CBC to check for inflammation or anemia 
  • urinalysis  to check the metabolic status 
  • a biochemical profile to check for kidney and liver disorder 
  • neck x-ray to check for a foreign object, mass or disorder in the esophagus 
  • chest and abdominal x-rays to check for disorders in the chest and abdomen 

Treatment options for cat drooling excessively

The following are the various treatment options for hypersalivation in cats depending on the primary problem causing it. 

  • for dental disease or oral mass – dental cleaning or surgery 
  • foreign object removal –  endoscopy, administered with sedation or anesthesia 
  • for oral infection or inflammatory conditions – antibiotics, systemic medication 
  • nausea – supportive therapy like fluids and dietary adjustments 
  • for liver and kidney disorders – proper identification through various laboratory tests should be made before any therapy is given 

If your cat is drooling excessively suddenly, you may do a quick visual inspection to assess if it was due to oral trauma, injury, or a foreign object. However, you should do it with great caution as your cat may become aggressive. Observe her attitude and behavior and if the drooling becomes worse. She may become agitated, reclusive, and may lay next to the water bowl

If your cat is not vomiting, try to give her water to drink. If the signs of the sudden excessive drooling are resolved in a few hours,  you may not bring her to the veterinary clinic but make sure to inform your vet about the incident. 

You can prevent hypersalivation by making sure that your cat is vaccinated for rabies, having regular oral exams, and practicing dental hygiene. Make sure to keep toxic items like insecticides, detergents, and harmful chemicals away from your cat. 


If your cat is drooling excessively and suddenly,  you should promptly assess it by doing a visual inspection if the cause was injury or foreign object ingestion.  If the hypersalivation persists for an extended period your cat should be brought to an emergency veterinary care facility. However, if the symptoms are resolved after a while and your cat is acting normal, there is probably no immediate cause for alarm.
