These Precious Tails Plaid High Density Foam Steps Pet Dog Stairs give pets easy access to their favorite spots and are especially helpful for seniors that have trouble jumping and cats or dogs with joint problems. This product is made from a lightweight foam that makes the dog stairs easy to move but sturdy enough for any size paws to run up or down. The bottom of these stairs is made from a non-slip material which helps keep the steps in place while your pet climbs up and down. The ultra-soft fleece fabric can be removed for cleaning and is machine washable.
