i recently switched toby's food from purina to iams because, being a poor 20 yr old living on her own, it was on sale so i went for it. but toby i don't think is very happy with the change and he barely eats it. he'll just stare at it, then look at me like "seriously??" has this happened to anyone or does anyone have a picky eater like this? i bought a large bag of the food and i don't want to just run out and buy something and have wasted that money on the food. is there a way i can get him to eat?
