Hey guys. I have a bit of a problem involving my 7-year-old cat who does have a bit of dental problem. This morning is the first time that I saw drool down his face (I don't really count yesterday as there was only a bit on his whiskers) and now I'm wondering if that's normal in a cat. There was no puddle. He eats, sleeps, poops, and acts completely fine aside from that. Not too sure how to know if he's lethargic since he's not really an active cat in the first place.
