At the APPC https://www.appcpanama.org/ the biggest animal we work with (in fact the largest land animal south of mexico in the americas!) is the Baird’s tapir. She is HUGE and STRONG and SMART and it can be very difficult to make toys for her that will last!
when Paula Te visited though, we re-taught ourselves how to weld and got busy making a big strong enrichment feeder for her!
