Try to entice him to eat by pouring low sodium chicken broth on his food and warming it in the microwave. Be sure to stir it and check for hot spots, like you would a baby's formula. You can offer the chicken broth instead of water to help keep him hydrated or give him unflavored Pedialyte. If he isn't significantly better by morning or if he gets worse, vomits more, develops diarrhea, fever or anything else abnormal, get him in to a vet right away. He may have eaten something that didn't agree with him, but I worry he may have swallowed some non-food item that could be causing an obstruction. Left untreated, an obstruction could be life-threatening.
