Animal Enrichment


Animals in nature have to work for a living – to find food, to make nests, and to find shelter. Play is another natural activity. Life for the animals at the Houston Zoo is more predictable than in the wild. That’s why our keepers use enrichment to create variety through work and play.

At the Houston Zoo, we choose items and activities that are safe and encourage natural behaviors, such as:

• Giving orangutans branches of plants like mulberry and bamboo to make nests

• Hiding crickets in a cardboard box for our maned wolves to discover

• Running treats like chickens down a zip line over the lion exhibit to help our lions run, jump, and reach

• Giving tasty ostrich eggs to our very appreciative Komodo dragon, Smaug

• Making ice pops for carnivores and primates out of their favorite foods to help them stay cool on a hot day

How about some Christmas in July! The zoo received a generous donation of christmas trees from Whole Foods back in December. The different animal departments put them out for the animals to enjoy. Below you can see the Spectacled Bear with his hanging tree as well as a special glimpse at the Attwater Prairie Chickens checking out their festive enrichment. (2 photos) ... See MoreSee Less

Oh Olive what have you gotten into now...! Looks like this anteater is having a fun time checking out her enrichment box. Keepers smeared mango flavored baby food on the inside. By the time she was done with her inspection, one would have seen her climbing into the box and then flipping over on her back while still playing inside the box. ... See MoreSee Less

Feeding 6000 Hungry Mouths

© Houston Zoo/Stephanie Adams

The Houston Zoo has more than 6,000 animals to feed every day. The Zoo’s Animal Nutrition staff begin work at 5 a.m. so they can have meals prepared and delivered to the animal sections in time for breakfast. There is a whirlwind of activity in their building including thawing meats, chopping produce, sorting insects, and loading bales of hay and bags of grain.

Each of our animals receives uncompromising excellence in animal care including the best in nutrition. The dietary needs of our animals are almost as varied as the animals themselves. All animal diets are developed in consultation with a specialist in exotic animal nutrition and are regularly analyzed for nutrient composition in order to ensure the optimal health and welfare of our animals. Diet sheets are kept for every animal that outline the type and amount of food needed every day of the week.

The Animal Nutrition building boasts a state of the art kitchen that includes commercial-grade appliances and equipment, 540 square feet of freezer space, three walk-in coolers, 2,000 square feet of dry storage, and a 4,000-square-foot hay barn. Despite all the activity, at the end of every day the kitchen is left clean and sparkling.

Veterinary Care

What’s it like to be a veterinarian at a zoo? Every single day is a different but exciting challenge! The vets and support staff at the Houston Zoo work hard every day to ensure the health of our more than 6,000 animals. This includes:

Preventive care: Animals are examined routinely and given vaccinations for diseases such as West Nile, Rabies, Tetanus, and Distemper. Yes, this also includes fecal examinations to detect parasites before they become a problem!

Quarantine: Before a new animal is allowed into an exhibit, we must be sure it is healthy. All new animals are quarantined and receive a thorough examination.

Wellness physical examinations: Veterinary staff performs routine physicals on Zoo animals, including blood analysis, dental work, TB testing, and bank blood serum or plasma for future needs.

Treatment: When an animal has a medical problem, the vet staff is there to help by providing necessary medical treatment, including diagnostic testing, writing prescriptions, and doing surgery. We also consult with outside specialists when needed to be sure all our animals receive the best care possible.

Meet the Vet: Dr Joe

Dr. Joe Flanagan

Dr. Joe is one of 4 vets at the Zoo and has tended to the health care needs of Houston Zoo animals since 1982. His reptile and amphibian expertise has taken him to the Galapagos Islands, home of the Charles Darwin Scientific Station and Galapagos National Park, where he provided assistance in the health assessment of birds and tortoises. He also donates his time along with the other vet staff (in partnership with the NMFS Galveston Lab Sea Turtle Facility) to help injured sea turtles, removing hooks, rehabilitating them, and releasing them into the Gulf!
