Ramp Cover Designed with Guinea Pigs & Owners in Mind! Our Guinea Habitat Ramp Cover is crafted from PVC-lined canvas to protect your guinea pig's sensitive feet while walking up and down the metal ramp. The canvas material also provides traction, preventing slips and slides. The Ramp Cover is secured with hook and loop tabs, and can easily be removed for hand washing. It's durable and leak-proof, so it will stand up to plenty of little feet scurrying over it.
