Lions Eating

It’s important to provide lions with food that stimulates their natural behaviours, as well as with the health benefits of chewing directly off of a hide.

Meerkat & Snow

Meerkats love digging their food out of a snow pile! The zookeepers will bring snow into their enclosure in the winter and stuff food in it.

Here an elk was given a bale of hay to eat and destroy (and apparently sit in).


Environmental Enrichment Devices

Giraffe Door Knocker

Giraffe Playing with Door Knocker

Food can’t always be used for enrichment, or else the animals might become obese, resulting in decreased health. Here, the giraffe uses its lips to play with some door knockers.

Snow Leopard Ultrasound

Snow Leopard Ultrasound

Dr. Whiteside performs an ultrasound on one of the snow leopards at the Calgary Zoo. The assistant feeds the snow leopard during the procedure so that in future she will know that this interaction is a positive experience.

Polar Bear Blood Collection

Polar Bear Blood Collection

A polar bear at the Toronto Zoo is being trained for blood collection. The assistant feeds him during the procedure so that he will have a positive association with blood collection in the future. This is a form of enrichment for the polar bear.

Lion Injection Training

Lion Injection Training

Dr. Whiteside performs an injection on Baruti the lion at the Calgary Zoo. The assistant feeds Baruti evaporated milk – his favourite! This ensures that Baruti associates receiving any sort of injection as a positive experience, reducing the amount of stress he endures.
