Pulse Brands Cage Liners are perfect for your small animals cage. Dimensions: Each pad measures 22 by 22 inches (56x 56 cm). 5-Layer Leak-Proof Design: Each pad comes with five layers to ensure leak-proof performance. The anti-streaming top layer offers a quick-drying quilted surface that locks in wetness, reduces odor, and prevents tracking. The surge layer keeps the liquid flowing in the right direction, while the sponge-like core provides maximum absorption and turns liquid into a gel upon contact. The last two layers of the leak-proof pet-training pads--the locking layer and the protective plastic lining--keep floors safe from damage.
