My chameleon cage is kind of like the castle .But I only use it when the cats are in their last instar and start walking away from their food.. I let them go inside the screen enclosure. ( I sterilize it outside.. I spray it down with a 10 percent bleach solution,hose it off and dry it in the sun.)
Basically for me at home it's
1. eggs and newborns in the deli type containers
2Older cats in the hermit crab cages
3.Those ready to pupate and chrysalises in the screen enclosure.
At school I let them pupate on the lids of the hermit crab cages then I hang them up in a really big screened enclosure we have there.
Everyone has their own method that works best for them
(I wish there was one perfect method!!)
I can tell you this, though.. I bought a lot of stuff when I first started.. and I am STILL buying stuff.
