The Kerbl Window Mattress offers a cosy and comfortable spot for your cat to enjoy the view. Featuring a self-heating sleeping surface that reflects your feline's body heat and repels the cold from the windowsill, this mattress ensures maximum comfort. It has a rubber coating on the back for added stability and is made from 100% Polyester. Its dimensions are 60x26x2cm, and the cover is removable thanks to a zip, making cleaning easy.
