  • Patent number: 5724911
    Abstract: A cushion for a pet, preferably a cat, comprising a bed formed from a sheet comprising a plurality of layers of raw unwoven, uncovered 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 sheet 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 is then cooled until the second fiber solidifies, attached to the adjacent fiber. The resulting material is a matted web of layered, electrostatic fibers that is subsequently cut into a right cylinder having a closed end of suitable size, such as large enough to accommodate a sleeping cat. The cylinder wall is then folded down on itself from its open end to form an annular upright wall having an inside layer and an outside layer, where the outside layer compresses the inside layer to form a more rigid wall.

  • Patent number: 5515811
    Abstract: The present invention is a cushion for a pet, preferably a cat, comprising a pad of a plurality of layers of raw unwoven, uncovered 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, electrostatic 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.
