[on 'Hammy Hamster'] Casting is simple. The animal has to look right and can't be too crazy or wild. Acting talent doesn't figure into it - you can't teach them to act. We've never been accused of being mean to the actors - we treat them with kid gloves. If [Guinea Pig] sneezes he gets immediate medical attention. We have veterinarians on duty at the set. One day we thought Hammy might be having heart problems, so the vet gave him a hamster ECG, and prescribed him some heart medication.
