Durable, clear-as-glass and economical—these cages come in a range of sizes that allow you to create ideal habitats for a variety of small animals. The impact-resistant plastic cages feature rounded corners so cleanup is a breeze. Use the smaller cages to house hermit crabs, large insects, salamanders, newts and small fish. Larger cages are roomy enough for terrariums, aquariums and small mammal habitats. Each includes a self-locking, fully vented lid. Lids feature convenient snap-seal access hatches for feeding and maintenance. Knockouts in lids allow for routing aquarium airline tubing-facilitating use of airstones, filters and other air-driven accessories.
