  • Expandable pet cage and method
    Patent number: 5960744
    Abstract: An expandable pet cage for animals, and a method for house-training pets of various sizes comprises two complimentary compartments that are in telescopic relation to each other, thereby providing an adjustable composite volume to house a pet. The adjustable composite volume facilitates using the natural instincts of the pet to resist excreting in the volume of the confinement, thus resulting in house-training the pet. The adjustable volume also can be relied on to hold an animal securely and safely during transporting, and provides an efficient enclosure for drying a pet after grooming. Also, the adjustable composite volume provides the pet owner with the convenience of only having to purchase one cage even if dogs of various sizes are to utilize the cage at different times and for different purposes.
