Abstract: A modular play structure for animals has base and platform pieces with connector mechanisms, such countersunk bores, spaced apart by a standard distance. Thus platforms and bases can be oriented in multiple directions and are interchangeable. Columns space the bases and platforms vertically. Columns may be of varying height, preferably with different heights described by a common factor. Stacked columns are connected end-to-end with a spacer of the same thickness as a platform interposed therebetween. Columns are oriented in the same direction with female and male ends connecting with platform, base, and adjacent columns.

Abstract: The invention presents a harness assembly for lifting and supporting an animal in mobility. The assembly comprises a front and rear harness sections releasably attached by a lifting leash. Both the front and rear harness sections can be used independently. Both the front and rear harness sections are comprised of upper and lower sections releasably attached to one another. The rear harness section lifts the animal from both the hips and waist resulting in less stress than other devices.
