Chef Yohn Sutton has a lot to do in his kitchen each day. He washes vegetables, chops fruit, and bakes sweet potatoes. He also works with unusual ingredients, like crickets, mealworms, and mice!

Sutton is the nutrition keeper at the Virginia Zoo. Each day, he preps meals for the zoo’s 670 animals, ranging from millipedes to African lions. Each species follows a specific diet.

Sutton makes sure that every animal gets the correct vitamins and nutrients. To do this, he prepares thousands of pounds of food every week! We spoke with Sutton to find out what it takes to feed an entire zoo.


How did you become a zoo chef?

I studied animal nutrition in college. After graduating, I joined the Virginia Zoo as a zookeeper. I cared for animals by feeding them, cleaning their enclosures, monitoring their health, and providing activities to keep them occupied. In 2016, I began overseeing the zoo’s nutrition center.

What’s a typical day like for you?

My day starts at 6:45 a.m. First, I prepare vegetable meals for the plant eaters, like rhinos, tortoises, and sloths. I wash produce thoroughly. Then I prepare meat for the meat eaters, like tigers, cheetahs, and lions. They eat ground meat and frozen rabbits. 

Finally, I have to clean up. I wash at least 200 dishes—some by hand. 


How do you know how much to feed the animals?

We calculate the amount each animal should eat each day. Since zoo animals are less active than those in the wild, they don’t need to eat as much to stay at a healthy weight. Our five white rhinos eat the most because they each weigh around 4 tons!

How is food preparation for animals different than for people?

The biggest difference is that I don’t add seasoning—no salt or spices.

Most animals have very specific diets based on the food available where they live in nature. For example, we give the sloths bell peppers, because they have similar nutrients to the flowers sloths eat in their rainforest habitat.


Does the zoo have any picky eaters?

We have a type of ape called a gibbon that is picky about food texture. He wouldn’t touch raw sweet potatoes. He was underweight. I started cooking the potatoes to make them softer and sweeter. Now he’s chowing down and thriving!


What’s your advice for kids interested in a career like yours?

Seek out hands-on experiences. You can start by closely observing how animals eat. For instance, tortoises use their sharp beaks to tear food. So we give them large pieces of food they can rip apart. But birds need smaller pieces because they can choke on big chunks. If you love working with animals, this is a great job for you!
