The Importance of CREW’s Domestic Cat Research

Guest blogger: Zoo Academy student, Jane Collins

The Cincinnati Zoo & Botanical Garden’s Center for Conservation and Research of Endangered Wildlife (CREW) is famously known to the world for its hard work on saving endangered plants and animals. Whenever people learn about CREW, they hear about the projects on polar bears, Sumatran rhinos, wild cats, and many plant species including autumn buttercup, four-petal pawpaw, and Avon Park harebells. You learn a lot about how important these projects are, but I believe there is one important aspect of CREW that is not as well known to Zoo visitors as it should be. I’ll give you a hint, re-read the title!

That’s right. I’m talking about cats. I don’t mean the wild African lion, cheetah, or tiger that you may have been thinking about. I mean domestic cats. CREW’s Domestic Cat Research is actually important to saving endangered big cats in the wild. These special cats help CREW with a number of things, including testing a contraceptive vaccine and conducting oviductal artificial inseminations and embryo transfers.

The cats in this program are given vaccines for common diseases and are spayed and neutered when at the appropriate age so they are completely cared for. CREW volunteers take the time to socialize with the cats also so they are very affectionate cats and are never neglected.

As a Zoo Academy student, I personally have had the opportunity to spend time with the cats and see up close how well they are treated.  Washing cat dishes, litter pans, animal carriers, and a few other responsibilities may have not been the finest experience, but I liked that I was making even the smallest contribution to the care of the cats. I also was able to spend quality time with most of the cats playing and relaxing, whichever the cats preferred for the day.  I had a great time learning a few of the cats’ individual personalities. One cat physically demands love and affection by climbing right into your lap. Another is very vocal. And another cat even loves water.

My favorite cat was a three-year old grey tabby with black stripes. He was the largest male domestic cat I have ever seen and looked like he belonged deep in a dark jungle rather than at a zoo. At end of my time at CREW, he was up for adoption. I couldn’t bring myself to part with him and decided to take him home. His new name is officially Chaz. He likes to follow me around EVERY square inch of my house and cries when I’ve gone too long without petting him. He is a loving member of my family. It is very cool to have a cat from the Cincinnati Zoo that has contributed to research that helps to save endangered wild cats.

A Study to Honor Suci the Sumatran Rhino

The loss of our female Sumatran rhino “Suci” to iron storage disease just over a year ago on March 30, 2014 was a devastating blow to the Cincinnati Zoo’s Sumatran rhino breeding program. Iron storage disease is an insidious disease affecting many wildlife species that are maintained in zoos, ranging from marine mammals to birds. In addition to Sumatran rhinos, black rhinos are susceptible to the disease, whereas white rhinos and Indian rhinos remain largely unaffected.

The disease is extremely challenging because we do not know how to prevent it, diagnose it or treat it. The only known cure for the disease is frequent, large volume phlebotomies (blood collection), but nobody knows how much blood to draw or how often it must be removed to keep a rhino healthy, and it is difficult to perform phlebotomies without anesthesia. The best method for monitoring iron storage disease is to measure serum concentrations of ferritin, a protein involved in iron transport and storage, but ferritin can be species-specific, so an assay for humans or horses may not work accurately in rhinos. Such was the case with our Sumatran rhinos.

However, thanks to a dear family committed to helping rhinos that wanted to make a gift in honor of Suci, CREW has embarked on a new study to develop an assay specific for measuring rhino ferritin. The first step – isolating the rhino ferritin protein – is complete, and our goal is to have a functional assay by this coming summer. Our hope is that the assay will be used to monitor iron storage status in many rhinos throughout North American zoos to ensure the disease is detected before the rhino becomes sick.

This project was made possible by the generous donation of Mr. and Mrs. Jeremy S. Hilton and Family.

Paws Up for Polar Bears! Celebrating International Polar Bear Day

Today, let’s celebrate International Polar Bear Day with some fun facts illustrated by some of our own bears, past and present.

Polar bears are survival specialists in an extreme environment—the Arctic, where winter lasts six months and temperatures average -30ºF. Their large body size, thick fur coat and several-inch layer of blubber provide insulation from the cold, in and out of the water.

Here we can certainly get an idea of just how big a polar bear can be. Reaching weights up to 1,500 lbs, a large male can reach heights of more than 10 feet when standing up on its hind legs.

Check out those paws! Each one is the size of a dinner plate! They act like snowshoes, spreading out the bear’s weight as it walks across the snow and ice.

Polar bears have super sniffers. The polar bear can sniff out seals, their favorite prey, from miles away and even detect seals that are hiding underneath several feet of snow.

Their streamlined shape, partially webbed front paws and buoyant layer of blubber make polar bears champion swimmers. In the wild, bears are able to swim for hundreds of miles at a time between ice floes, from which they hunt seals. As our global climate warms, the sea ice continues to shrink, making it increasingly difficult for polar bears to hunt seals and reproduce.

The Zoo partners with Polar Bears International as an Arctic Ambassador Center to help save polar bears and their habitat by reducing carbon emissions to curb climate change and encouraging our supporters to do the same. Here at the Zoo we are doing our part to use energy more efficiently by generating renewable energy through solar panels and geothermal wells and employing green building practices.

We also have a brand new Red Bike Station located at the Zoo’s entrance. Next time you come to the Zoo, consider riding a bike to save on fossil fuels (once all this snow and ice is gone, of course). Check out some other ways you can take action for polar bears suggested by Polar Bears International.
