  • Patent number: 5363804
    Abstract: The present invention is a cushion for a pet, preferably a cat, comprising a pad of a plurality of layers of raw unwoven polyester. Each layer comprises a solid first fiber and a second fiber that has a core and a sheath surrounding the core. The sheath has a lower melting temperature than the core. The pad is then heated to the temperature, where the sheath of the second fiber melts and sticks to the adjacent fiber, whether a first or a second fiber, and then cooled until the second fiber solidifies, attached to the adjacent fiber. The resulting material is a matted web of layered fibers that is subsequently cut into a pad of suitable size, such as large enough to accommodate a sleeping cat. The edge of the pad is bound by sewing or heat treatment.
