I haven't seen this size of acrylic tray for pets anywhere else. ◾️Size (Outer Dimensions) W: 460mm D: 550mm H: 100mm Acrylic width: 3mm Recommended for birds, squirrels, tegus, and rats, especially for those who keep sugar gliders. When used in conjunction with SANKO's Easy High 37.40 High and Clear Cage Cover, it effectively prevents food and droppings from scattering, making cleaning very easy. ※The product is the acrylic tray only. Cages and sheets are not included. ※This product is a new, unused item, not the one in the photo. The photos are for illustrative purposes only. It may be slightly warped due to storage conditions or temperature, but it will return to its normal shape with regular use.
