OK Bear,
-- not a vet, but ---
He should at least be .......
If he's not, and hasn't for a couple days...he's dehydrated and/or in kidney failure. Or he's ...... on your rug.
In any event, get him some water now if you think he's dehydrated. Or maybe just get him to a vet.
he was at the vet just yesterday? let's hope they would have diagnosed anything that serious
