While it seems like it’s super common to hear about dogs drooling, believe it or not, cats drool, too, it’s just less obvious and generally not as often. Cats sometimes drool when they’re being held or pet, largely because they’re so happy you’re giving them attention! Don’t sweat it, though, if your cat doesn’t drool, because not all of them do. If you’ve noticed your cat drooling in other situations, though, it could very well just be a normal reaction. We spoke with two vets to get their take on why cats drool when you pet them and if drooling is ever a problem.
