Yep. My Tweetie has been taking his drooling to a new level as he's entering his seniorhood (will turn 10 later this year). I don't even have to pet him. If I walk past him or look at him in the eyes, he'll meow loudly at me, then immediately scrunch his eyes tightly shut, start purring loudly, and drooling. This loud purring will go on ad nauseum.
If I actually stop to pet him (as I inevitably HAVE to), he'll reach out with his paws and "grab" my arm, pulling it close so he can wrap himself around it as his "blanky", and will start nuzzling and licking my arm, all the while cooing and crooning with his eyes tightly shut... and drooling.
Silly cat.
