WHAT THIS IS: This is a Medium rabbit/bunny hay feeder and litter pan combo. This is one of our styles from our original Hop Box line. This is the perfect size for 1/2+ bunnies. The pan covers the inside of the frame so pee doesn't get onto the frame! MATERIAL: It is made from kiln dried Pine, which is safe for rabbits. The color of the pan is usually grey or tan. MEASUREMENTS/SIZE: The size of the feeder/litter pan combo is 20" long by 21" wide/deep by 14 1/4" high (with feeder and base). The size of just the pan itself is about 19" long by 14" wide by 4 1/2" high. ADD-ONS: - Mesh Insert: vinyl coated, waterproof, wire mesh grate insert is perfect for keeping urine and droppings from being stepped. It can be easily rinsed off and cleaned. The mesh squares are 1/2". - ENCLOSED feeder has the sides enclosed so rabbits can't pull out hay from the hay feeder while outside of the pan (less dowels) - NON-ENCLOSED feeder has dowels all the way across the feeder from left to right. SHIPMENT: Due to the size of the feeder/litter pan, the feeder detaches from the litter pan for shipping. It is attached by 4 screws and can be reassembled with a screwdriver. *We've been selling these feeders since 2015, buy with confidence!
