After only a few sessions, Ollie is happily targeting to a stationary mat and following a target stick. The mat can now be placed on a scale and Ollie can be easily weighed. He also knows verbal cues like “up”, “down” and will be able to go to his “mat” from a distance. Spins and twists can be cued with the target stick or a hand motion. Prior to enrichment and training, aggression was an issue between the 3 male otters. When I first started working with them, they would also hiss at and charge me (sometimes latching on to my shoes with sharp teeth)! This no longer happens!
