  • Patent number: 5913750
    Abstract: A regulated and effective means of exercising cats, which also serves as a cat perch and central cat feeding and hygiene station has a frame constructed of conventional dimensioned timber which supports a horizontal perch in cantilever fashion. An inclined treadmill with a closed loop belt encircling a plurality of rotatable rollers extends between a support surface and the perch. The cat makes his way to the perch by climbing the treadmill, which may be set at varying inclinations to suit the cat's weight and strength to obtain the desired treadmill time for a particular perch entry. The treadmill and the perch are covered by bent sheets of plastic, which confine the cat and require the cat to traverse the treadmill rather than jumping to the perch. The perch may be fitted with a pivotable door to temporarily retain the pet within the perch enclosure for limited times.
