Vinnie did this to me the day I thought was "the day" and we were to go after school. From the momoent he was up, he was perky (perky for Vin is a stretch, but you know what i mean) Everything I saw, including him on the couch when I got home, said today is not the day. He couldn't step up 6" without pain. SO, we went to see the vet as scheduled, and he told the vet and staff that today was not the day. Craziest thing I ever saw. And he did not go that day.
