Hello! I brought my green cheek for a wellness check and my vet suggested I switch his food from the Zupreem fruitblend to Goldenfeast goldn'obles. I mixed them and have slowly been removing the fruitblend. Yesterday I removed the fruitblend. He refused to eat his new food. Around 12pm I got worried because my vet said that if he hasn’t eaten by that time to just give him his old food. Is there any other way to get him to eat his new food? I just want to give him a healthier option.
