I have a goldfish and already that is a lot of work to care for. The idea of having chickens and mealworms is nice but I hate the early risers. My son wants more pets but until he is old enough to really help out with them I have to say No. It is now 10:30pm and I am only, finally sitting down to do something for myself. I am very interested in the idea that they can eat polystyrene.
