1. Make sure rough edges are sanded well (a Dremel is good for this).
2. Loops must be small enough so animals can’t get them over their head (calves), but large enough to manipulate to open the apparatus.

Ocean Park Hong Kong bottlenose dolphins cooperating with trainers to open the feeder.
Monitoring and studying the cetaceans' behaviour as they interact with enrichment allows us to understand their preferences, and even helps us to learn more about them as a species.
Several papers have been published on bottlenose dolphins' response to the cooperative feeder: find them at the links below, and get in touch if you'd like access to copies!
