Boxiecat's Light But Mighty™ philosophy: Boxiecat Air™ litter is light on what you don’t want but mighty on what you need, because Boxie believes you should experience lightweight litter without compromising on performance. AirTight™ clumps lock in odors, scoop easily, and don’t crumble. Enjoy a super-clean litter box while saying goodbye to weight, odors, and dust. Boxiecat Air™ is plant based, renewable, biodegradable, sustainable, and USA sourced. (Limit 1 per customer. Offer good single visit only. Email address required upon redemption.)
