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.

Meet Some New Faces at CREW

Welcoming Two New Post-Doctoral Fellows

Two new post-doctoral fellows, Dr. Lindsey Vansandt and Dr. Anne-Catherine Vanhove, were welcomed to CREW in the fall of 2014.

With funding support from the Joanie Bernard Foundation, Dr. Vansandt will be working with Dr. Bill Swanson, CREW’s Director of Animal Research. Dr. Vansandt obtained her Doctor of Veterinary Medicine degree from the University of Missouri and her Doctor of Philosophy degree from the University of Maryland (in collaboration with the Smithsonian Conservation Biology Institute). Her Ph.D. studies focused on characterization and propagation of spermatogonial stem cells in domestic cats as a model for conserving endangered cat species. Dr. Vansandt also has experience working in veterinary emergency services. At CREW, she will be conducting studies to improve the health and welfare of feral and shelter cats as well as helping to apply oviductal AI for propagation of endangered felids.

With funding from the Institute of Museum and Library Services (IMLS), Dr. Vanhove will be evaluating survival of plant samples in CREW’s Frozen Garden under the supervision of Dr. Valerie Pence, Director of Plant Research. Dr. Vanhove will complete the second phase of the IMLS project, focusing primarily on the survival of shoot tips and gametophytes after long-term storage in liquid nitrogen. She recently received her Ph.D. from the Division of Crop Biotechnics, Katholieke Universiteit Leuven, in Leuven, Belgium. Her thesis work with meristem culture, stress physiology, and cryopreservation makes her well suited for the IMLS project.

The University of Cincinnati/Cincinnati Zoo Connection

CREW has had a long-standing collaborative relationship with the University of Cincinnati’s (UC) Department of Biological Sciences, but today it is strengthened by two promising young scientists who split their time between CREW and UC. Corrina DeLorenzo and Megan Philpott are both enrolled in UC’s Ph.D. program under Drs. Ken Petren and Theresa Culley, respectively, but they are conducting much of their dissertation research at CREW.

Corrina earned her bachelor’s degree at Miami University, with a double major in Zoology and Environmental Science. As an undergraduate, she became involved in research evaluating the population genetics of the Italian wall lizard or “Lazarus lizard” in the Cincinnati area. After graduating, Corrina was accepted to CREW’s summer internship program, working with Dr. Erin Curry on the Polar Bear Signature Project. She was recruited into UC’s graduate program in January 2014. Since starting her Ph.D. research, Corrina has identified multiple antibodies that detect specific proteins in polar bear feces in an effort to develop a polar bear pregnancy test.

Megan received her bachelor’s degree from UC in Biology and was also an intern at the Cincinnati Museum Center, managing the Museum’s Philippine Bird Genetics project. Her Ph.D. research is part of the Plant Lab’s IMLS funded project to evaluate samples that have been stored for years in CREW’s CryoBioBank for genetic changes that might have occurred over time. In April, Megan was awarded the Botanical Society of America’s Public Policy award to attend Congressional Visits Day on Capitol Hill. There, she learned about communicating science to policy makers and met with the offices of Ohio Senators and Representatives to request their support for increased federal funding of scientific research, using CREW’s research as an example of the importance of federal funding and support.

P&G Wildlife Conservation Scholars

In 2011, CREW established a partnership with the Ohio State University’s College of Veterinary Medicine to train veterinary students in conservation sciences with funding support from Procter & Gamble Pet Care. This past summer, two OSU veterinary students, Kelly Vollman and JaCi Johnson, were selected as P&G Wildlife Conservation Scholars.

Kelly worked with Dr. Monica Stoops analyzing urinary testosterone and glucocorticoid concentrations to determine if the pattern of excretion could be used to predict gender, parturition date and assess fetal viability during Indian rhino gestation. Kelly analyzed urine samples collected throughout seven Indian rhino pregnancies that resulted in three male and four female calves. Six of the pregnancies ended with the birth of live calves, whereas one pregnancy ended in a stillbirth, a relatively common occurrence in this rhino species. By learning more about the endocrinology of pregnancy, results from Kelly’s study will help establish physiological markers to improve pregnancy outcome in this species.

JaCi worked with Dr. Bill Swanson to investigate cat sperm vitrification as an alternative to standard slow freezing methods. Vitrification involves ultra-rapid cooling to avoid ice crystal formation and form a “glass” instead. For this study, JaCi collected semen from domestic cats (and one ocelot) and compared vitrification in a sucrose solution, with direct pelleting in liquid nitrogen, to slow freezing with glycerol in straws over liquid nitrogen vapor. Post-thaw sperm motility and acrosome status were similar between methods and 25% of domestic cat oocytes were fertilized following insemination with vitrified
sperm. This simplified approach to cat semen preservation may be particularly useful for field biologists working with felids in the wild.

Supporting Black-footed Cat Research in South Africa

One of the world’s smallest cats, the black-footed cat is found only in the southern African countries of Botswana, Namibia and South Africa. It lives in dry, open habitats such as desert, savanna and scrubland. Due to its extremely shy and evasive nature, little is known regarding the black-footed cat’s status in the wild, though it is considered to be the rarest cat in Africa.

The black-footed cat is one of the five small cat species with which the Zoo’s Center for Conservation and Research of Endangered Wildlife (CREW) works on its Small Cat Signature Project. In addition to conducting zoo-based research on the reproductive biology of the black-footed cat, the Zoo also supports field research in South Africa.

Since 2004, a group of scientists and veterinarians working together as the Black-Footed Cat Working Group (BFCWG) (http://black-footed-cat.wild-cat.org/) have been studying black-footed cats in South Africa. The BFCWG aims to conserve this rare cat species by furthering awareness and conducting multidisciplinary research on the species’ biology, distribution, ecology, health, and reproduction over an extended period.

Once a cat is captured, researchers take a variety of measurements and samples are taken and fit a radio collar. Over time, this generates valuable data regarding the behavior, ecology, genetics, and health of the wild black-footed cat population.

Additionally, sperm collected from wild males can be imported into the United States (once frozen) and used to artificially inseminate captive females to infuse genetic diversity into the captive population.

This November, the Cincinnati Zoo & Botanical Garden helped to send Dr. Jason Herrick, a former post-doctoral fellow with the Zoo now working with the National Foundation for Fertility Research and as a Research Associate with the Denver Zoo, to South Africa to capture and replace radio collars on five male black-footed cats. At the same time, he is taking measurements and collecting samples.
