Cats drool when they are happy and relaxed, for example, drooling when petted can be normal behavior. Typically, these kittens adopt this behavior early in life, so it would not be unusual for an older cat to suddenly start drooling if they haven’t done so before.
5. Reasons why my cat drools
1. Dental disease and cat saliva
There are certain conditions, such as dental disease, that cause a burning sensation in the mouth. In such cases, salivation is also a good way to relieve or soothe irritation in the mouth or throat. Dental disease is a common cause of excessive drooling. About 85% of cats over the age of 3 years have tooth or gum disease.2. Respiratory conditions and cat saliva
Some cats that also develop viral respiratory conditions develop mouth ulcers, resulting in increased salivation.
3. Oral cancer and cat saliva
Although much less common than dental or viral inflammation, some cats also develop oral cancer which can occur anywhere from the tip of the tongue to the back of the throat. These conditions result in excessive and continuous drooling. This is a sign that your cat should have a thorough examination by your veterinarian, with special emphasis on oral conditions.
4. Foreign objects and cat saliva
Less often, excessive drooling may also be caused by a foreign object. Cats may also swallow a blade of grass, a sewing needle, or a small fish bone and the object may become stuck in the mouth or esophagus. They may paw at their mouth or try to vomit but the bottom line is swallowing is also uncomfortable and the cat will not be able to swallow normally.
5. Fear and cat drool
Some cats drool when they are overly excited, upset, or frightened. Salivation often occurs due to the anticipation of nausea and vomiting. Motion sickness can also be the result of driving a car or being scared. In any case, it usually stops at the end of the ride. This will not continue if your cat drools due to apprehension.
