I have raised Monarch butterflies for four years, and I have had great success using the big cube cage. The best feature is the drawbridge door which makes it so easy to add and remove cuttings to feed the cats, the door is out of my way while I clean the cage bottom and I can easily reach in to take my butterflies out to release them. Because it is so roomy, I have no worries about disturbing the chrysalises while still taking care of the caterpillars that are still eating the milkweed cuttings. I highly recommend this cage to successfully raise any variety of butterflies.
