Abstract: A bird toy for stimulating a foraging instinct by surrounding a treat on a platform on a main body with one or more substantially transparent rings rotatable and vertically slidable on the main body. In one or more rotative positions of the ring or rings turned by a pet bird, the ring or rings are allowed to shift vertically to make the treat accessible. A bottom platform allows a more difficult test, requiring the bird to lift the ring or rings to expose a treat on the bottom platform after rotating the rings to the correct position allowing the rings to be lifted.

Abstract: A knock-down type support stand especially suited for aquariums or other heavy objects employs double walled support legs that are each formed of inner and outer sleeves of tubing. Upper and a lower horizontal frames act as supports for the objects. Attached to each outside corner of both of the frames is a corresponding one of a plurality of vertical hollow sleeves, each of which is of the same cross sectional dimension as the outer hollow sleeves in the support legs. The inner sleeves for each of the support legs are inserted into the vertical hollow sleeves in the frames, while the outer hollow sleeves for the support legs engage the top ends of the vertical hollow sleeves on the lower frame and the bottom ends of the vertical hollow sleeves on the upper frame. The stand preferably uses tight, friction fit tolerances.
