Brief description: Similar idea as our treat mound, but easier to spread out the puzzles throughout the chimps’ enclosure
Materials: To make our puzzle we used pipe and fittings that were 1 1/4″ size. To make one puzzle, you will need approximately 6 inches of PVC pipe, 1 galvanized Floor flange, 1 threaded PVC cap, and 2 PVC threaded male adapters. You will also need PVC glue, PVC primer and zip ties.
Assembly instructions: Permanently attach a threaded male adapter to both ends of the PVC tube using primer and glue. Screw the cap on to one of the adapters- the puzzle will be easier to clean if you can unscrew the cap when you are finished with it. Zip tie the floor flange to the outside of the chimps’ enclosure caging (the flat side should be flat against the caging), doing your best to line up the hole in the flange with the hole in the caging.
How to use: Smear peanut butter inside the tube. To attach to the caging for use, screw the uncapped male adapter side into the floor flange (which should be zip tied to the caging).
Price: Approximately $20 per puzzle.
