yes it for SURE should have been a gradual change since you were going from a low quality food to a high quality food- his system is cleaning out all the old stuff. if it hasn't been too long since you made the change i'd backtrack and start putting more Iams back in his food- it should take 10 days to change them over. For the time being you can give him PURE canned pumpkin. you can get it in the baking section- it comes in a canned- says 100% pure pumpkin- this should help.
