If you can keep them in one or two large containers, it's easier to keep them clean. Early on, it helps to have sealed containers to keep moisture in, but once they're into the second or third instar, they need air flow. They grow faster and eat more if they are warmer, 80sF. Keep predators away. I like to have spare containers that I can move all the currently occupied leaves/plants into, add fresh leaves, and close them back up with as little interference as possible. Then you can clean that container thoroughly to be ready for the next cleaning. I clean cages at least daily to get rid of fras (poop) to minimize disease. When they are close to forming their chrysalis, I like to tape brown paper to the lid of the container in hopes they'll attach there and make transport easy. Some varieties insist on some sort of stick to attach to. Most important is to keep plenty of fresh food available and to bother them as little as possible during each molting period between instars. If a cat is hanging around on the wall not moving or eating, it's best to clean around it and leave it alone.

Let us know how things are going.
