This is an old photo (taken in 2004) that shows all four monsters munching their way through some tasty snack. Nowadays I hardly do that anymore, since they either throw it all up again or don't eat it at all. Both times it's a waste of good money. And I can use that good money on their regular food, which is quite expensive.
As you may know I'm not home right now (coming back from London today), but fortunately I have a fantastic neighbour who comes in every day to put fresh food and water down for my monsters. They certainly won't starve!
