Boo is always hungry. I feed him half a can of wet food morning and night, and he has dry food left out all day long. The problem is, he doesn't want to eat the dry food. I'll feed him his wet food in the morning, then a few hours later, he's screaming at me because he's hungry. He keeps trying to lead me to the fridge. I'm worried about over-feeding him. He's not fat, nor is he too skinny. I don't understand why he always seems to be starving when there's always dry food out for him. Why doesn't he just eat that??
