Abstract: Step4Paws actualizes the concept of using a modulated staircase to assist dogs and cats in getting up to and down from household furniture. Manufactured into various heights and dimensions, the modules can be used singularly or in conjunction with another or other module(s). This flexibility allows for tailoring to various specifics such as size or jumping ability of the dog or cat and to floor space limitations. Increased user-friendliness is an inherent characteristic of the design created by two main attributes: a wide, horizontal surface, and a soft, carpeted surface. Combined, these two attributes make for an inviting means for dogs and cats to ease the difficulty in reaching their desired destination. In fact, Step4Paws offers itself as a viable, attractive alternative to their favorite spot.
