Healthy cats do not drool. However, it
is common for cats to drool when they know they are going to be given an
unpleasant-tasting medicine or receive an injection. This is psychological. A
few cats will also drool when they are purring and very relaxed. It is
important to know what is normal for your individual cat.
Keep in mind that an animal who drools excessively and acts irrationally
could have rabies. Exercise great caution in handling such an animal.
The cornea, or clear part of the eye, is covered by a protective layer of
surface (epithelial) cells. Most destructive processes affecting the cornea
begin with an injury to this layer. Any irritative process, such as a foreign
body or cat
scratch, can cause a surface injury. Cats with prominent eyes, such as
Persians, are especially susceptible. Once the continuity of the epithelium has
been destroyed, the injury either heals spontaneously or progresses to a more
serious problem. The outcome...
Drooling accompanied by signs of ill health, such as watering of the eyes,
is quite likely due to a feline viral respiratory infection. Young cats with liver shunts
will drool excessively. Mouth infections and foreign bodies in the mouth are
accompanied by drooling. Heat stroke can cause excess salivation, as can
certain poisons (such as insecticides and arsenic).
Treatment: This is contingent on identifying the cause of the drooling.
