why does my cat drool when i pet him 1

Your cat drools when you pet him most commonly because he is happy and relaxed. This drooling typically happens when a cat reaches a state of pure contentment, causing the muscles in their jaw and lips to relax and release saliva. This behavior can also be linked to pleasant feelings similar to those experienced during kittenhood nursing. Cats may drool while purring, kneading, or being cuddled as a sign of deep trust and comfort. However, drooling can also sometimes indicate other causes, such as stress or anxiety, dental disease, or other health issues. Stress-related drooling is usually accompanied by signs like fear or agitation. Dental problems, which are common in cats over three or four years old, can cause excessive drooling due to irritation or pain in the mouth. If the drooling is occasional and occurs during petting accompanied by positive body language like purring and relaxed posture, it is generally normal. But if the drooling is excessive, constant, or comes with signs like bad breath, blood-tinged saliva, difficulty eating, or behavioral changes, you should consult a veterinarian to rule out medical problems. In summary, your cat’s drooling when you pet him is most likely a sign of happiness and relaxation, but keeping an eye on the amount and context is important for his health.
