I'll decide tomorrow morning when I test before breakfast. He seemed a little "off" today, not wanting his regular food, but eating it if I watered it down. Probably should try to get him into the vet and see if it's his teeth; he sometimes acts like this if his mouth is bothering him. He's had "good" dentals in that he's not needed extractions, but his teeth seem to "gunk" up quickly... Wish I could get the topical pain medication and keep it on hand -- that would be a good test to see if it's pain or something else.
