Meh, fine i'll just let him go hungry until the rat pups are big enough to interest him. After that he should be slamming them down. The evidence is overwhelming that this would be at my own risk and i'd rather just not take the risk and have to pay a vet bill later. As much as I want him to eat, a parasite would be much more damaging to his health than waiting another week or two for the rat pups to grow. Thanks everyone.
