well, I've mentioned before that all my guys each seperately. And if I can do it with 13 you can do it with 5. This is the only sure fire way to give 1) the proper food, 2) the proper amount of food and 3) to know who is eating, what they are eating and how much they are eating. They can be trained to eat morning and night in a carrier or behind closed dorors. I had to start somewhere and each one needed to learn the new routine when they came here. It is surprisingly easy.
