Keeping a pet secure in their habitat not only prevents surprises for unsuspecting family members, but also keeps them safe. An escaped pet can get injured or hide for days or weeks after the stress of their breakout. When this happens, they can become ill by slowly starving themselves of food, water or warmth. A properly secured, adequately ventilated reptile terrarium keeps everybody happy. Pets stay active and thrive in an enclosure topped by a reptile terrarium screen cover that allows air and heat to flow freely. Screen clips are also available in non-locking, locking, and heavy duty.
