While drooling is more common in dogs, did you know that cats sometimes drool, too? Many cats begin to drool when they are very relaxed and happy, especially when they are being petted. Drooling sometimes goes along with purring and kneading, and this behavior may stem back to kittenhood when kneading stimulated the mother cat’s milk production.
Cats may also drool when they are frightened or feel nauseous. If you have ever given your cat a bitter-tasting pill, you may notice drooling or foaming at the mouth. Your cat may even learn that the medicine will taste bad and begin drooling in anticipation. You should also be aware that cats may drool when they are having dental problems, and certain illnesses such as the calicivirus can trigger excessive drooling. If your cat does not usually drool and you are not sure of the cause or your cat’s drooling, you should contact your veterinarian for advice.
My own cat is a drooler, and will drool when I am feeding her treats and also when she is relaxed on my lap. This behavior doesn’t bother me because I know it is a sign that she’s happy. If your cat drools or kneads excessively, try placing a towel or blanket on your lap for your cat.
