Abstract
A hollow bone-type pet toy having defensive curves includes a body having a narrow mid-section and at least two hollow lobes extending therefrom. Each lobe tapers outward from the narrow mid-section to a wide end and has walls defining an inner cavity. In cross-section, each lobe wall is thinnest adjacent the narrow mid-section and tapers outward in thickness such that the wall is thickest at a distal end; at a distal end of an outer surface, the outer surface terminates in a defensive deflection curve that extends around a distal end of the wall; and at a distal end of an inner surface of each lobe wall, the inner surface terminates in the defensive curve. The defensive deflection curve is defined in two-dimensional space using a set of cubic Bézier curves. A pet's teeth are thus deflected by the distal ends of the walls when the pet bites the pet-toy.
