DIY Guinea Pig Tray Liner

Make a washable liner for your guinea pig’s cage! Measure the floor of the tray and cut a mattress pad and a decorative piece of fleece to the measurements needed. Sew the fleece onto the mattress pad. Measure the walls of the cage tray, cut strips of fabric to the sizes needed, and sew the strips onto the edges of the liner. Put the liner in the tray and fold the strips over each wall of the tray.
