why does my cat drool when she purrs

Your cat drooling when she purrs is generally a sign that she is very relaxed and happy. This behavior is quite normal and happens because when cats purr and relax, their muscles, including those in the mouth, relax as well, which can cause saliva to come out and lead to drooling. The release of feel-good hormones like endorphins and serotonin during purring can also stimulate saliva production. Some cats start drooling when they’re happy as a carryover from kitten behavior related to nursing. Drooling combined with purring, kneading, and relaxed body language usually indicates contentment and pleasure. However, if drooling happens excessively, constantly, or is accompanied by signs of discomfort or distress, it may indicate dental or health issues, and a vet should be consulted. So, in short, if your cat drools when she purrs and seems content, it’s a normal expression of happiness and relaxation.
