Training zoo animals to voluntarily participate in veterinary procedures through positive reinforcement is one of the most significant advances in zoo animal welfare in recent decades.
Cooperative care training transforms the veterinary experience for zoo animals from a stressful, often dangerous restraint procedure into a voluntary, food-rewarded interaction. The welfare benefits are substantial: anaesthesia risk is eliminated, animals show reduced stress indicators, and health monitoring can be conducted more frequently. Training also enriches the animals' environments by providing cognitive challenges and positive human-animal interactions. The welfare improvements from cooperative care represent one of the most demonstrable zoo welfare advances of the past 20 years.
