Tempered glass on the back promotes viewing and adoption by providing an unobstructed view of the cats and is more scratch resistant than acrylic, ensuring a clearer viewing surface. Units can also be positioned to allow maximum visual stimulation of the cats environment. These upscale units have an almond interior and offer a warmer and quieter environment that can promote less stress in cats than stainless steel. A standard 15 deep shelf maximizes space for cats and provides ample room for food and water bowls while allowing for optimal visibility of the cats through the glass. The wire grid front promotes airflow and improved animal health while also allowing for interaction with facility staff. The gates include an easy-to-use latch with an option for key locking latches. Long-lasting heavy-duty hinges are removable for deeper cleaning. The units can be configured in two or three tiers. Designed to be installed on a prepared base, these adoption units are perfect for installing on a deck, and when coupled with a soffit above they turn an entire wall into a space to showcase cats available for adoption. Units arrive fully assembled and the standard size is 28 x 28 x 28. The height is designed to allow cats to use the litter box in its normal posture for elimination. Side litter units are also an option. Custom sizes are available.
