Not to sound too concerned, but I'd make an appointment at the vet's. If Taz continues NOT to eat, he may develop hepatic lipidosis(a fatty liver). It can be fatal. We lost a cat in December to mild hepatic lipidosis. Nicholas stopped eating. We took him to the vet and his liver enzymes were thru the roof. He was jaundiced. And then he was gone, it all happened so fast. It is far better to err on the side of caution, I'd go to the vet.....
