Give your monarch butterflies and caterpillars the ultimate safe haven with this heavy-duty outdoor cage, built to withstand the elements and keep threats at bay. Crafted from ultra-strong nylon fabric-far more durable than conventional popup netting-it resists weather, predators, tearing, and parasitoids, ensuring your little charges thrive from caterpillar to butterfly.Designed with meticulous care, it features an extra seam of protection around the zipper. This clever detail prevents caterpillars from pupating on the zipper, avoiding damage when you unzip-so every chrysalis stays safe. Unfolding to 15 x 15 x 30 inches, it's tall and spacious enough to hold 4 large milkweed plants (up to 3 feet tall) and nurture up to 40 caterpillars at once. The generous interior means new butterflies can stretch their wings without risk of breaking, readying themselves for flight.Breathable mesh panels deliver excellent airflow, keeping the environment soft and comfortable for caterpillars. The side-opening door is a game-changer: it lets you access the cage without disturbing chrysalises on the roof. When it's time to feed or release, the large zipper opening makes it easy-and watch as butterflies often land on little hands and faces before taking off, creating magical memories. When not in use, it collapses for effortless storage, ready to be reused season after season. For anyone serious about raising monarchs, this cage is the ultimate blend of protection, convenience, and care. Color: Black.
