<p>The present patent application relates to an apparatus with rotating links for environmental enrichment and based on the presentation of a physical stimulus (locomotion). The apparatus is manufactured with a 12'' PVC tube (3 rings 20 cm wide), 22'' stainless steel (3 strips measuring 6x100cm), metal (cast iron) chains of 80cm for supporting the apparatus and making it of easier access from the floor (in the case of nursing animals), and two metallic devices (snap hooks) made of plated wire that allow the PVC rings to rotate independently. The apparatus comprises rotating links and a swivel-like, twisting element arranged between the rotating links to enable the animals to turn the links in opposite directions, or even to keep them stationary while another animal is playing on the link above or below.</p> |
