The sleeping mat is a versatile and practical choice for your cat, as it can be placed inside a carrier, on furniture, or on a cat shelf. It is essentially a padded, flat surface made of different fillings and covers. Since they come in a variety of sizes, they are ideal for large cat breeds like Maine Coons that wouldn't be able to fit in more enclosed beds. Plus, these beds are easy to clean - which is essential if you have cats or kittens who shed a lot of furs.
