I love this enclosure! I use it with the poopoo platter and it works really well. I wouldn't use this if you have a ton of caterpillars, but it works really great for me since I live in Southern California and have less of a need to bring caterpillars in out of the cold. I use this to rear a few at a time because I personally love it, and for educational purposes for the kids I teach.
The drawbridge door makes it super easy to add new food or cats, and especially easy to clean the cage. The poopoo platter helps with cleaning and so that the enclosure keeps it's structure when I need to move it. And I'll note that both products are much better and easier to use than the first round of similar items I got on Amazon, all of which had various problems that made them unuseable and even dangerous for caterpillars and various diseases.
Sourcing these items from a website dedicated to helping the beautiful species is really the best for them and us.
