How to stop your cat from drooling
Anticipate happy drool.
Cats often drool when they are happy and content, like when they eat catnip. Don't give your cat catnip if you don't want it to drool.
Also feed your cat on time so it doesn't drool when it's happily waiting for food. And put a towel on your lap when you pet your cat, because you can't prevent this type of happy drool.
