CREW continues to make progress in improving the success of artificial insemination (AI) for propagating endangered
cats. In recent research, we incorporated treatment with oral progesterone (Regumate) into our AI protocol for domestic cats to down-regulate ovarian function prior to ovarian stimulation. This approach allows us to control ovarian activity more precisely and conduct AI procedures on a fixed time schedule.
Our first attempt using this method in exotic felids involved our fishing cat named Ratana,who was incapable of breeding naturally after losing a front leg due to injury. Ratana was fed a small amount of oral progesterone daily for one month to suppress her ovarian activity and then treated with gonadotropins to induce follicular growth and ovulation. Laparoscopic AI of both oviducts with freshly collected sperm from our resident male, named Gorton, resulted in conception and the birth of a male fishing cat kitten after a 69 day gestation.
This kitten was the first non-domestic cat born following the use of oral progesterone for fixed time AI, and represents the fifth cat species (fishing cat, ocelot, Pallas’ cat, tiger, domestic cat) that we have produced with oviductal AI. This new approach could greatly advance our capacity to use AI for the genetic management of endangered felid species.

February 27th is officially INTERNATIONAL POLAR BEAR DAY, but some high school teens in Cincinnati and Aurora, Indiana have already made a significant impact on the lives of polar bears. They are winners in a bi-national contest sponsored by Polar Bears International (PBI). Project Polar Bear is a way for small groups of young people to make a big difference! This contest challenges teens to create community projects that reduce carbon emissions to lessen global warming and, therefore, protect the polar bear’s Arctic habitat.
Overall, 23 teams from 12 states completed their projects for this contest. [Read more →]

As one of Polar Bears International’s official Arctic Ambassador Centers, CREW is involved in PBI’s Project Polar Bear.
The Care Bears team has created MyActions.org, a website that encourages individuals and organizations to enter energy usage behavior. The information entered is tracked and calculated to estimate CO2 savings.
You can track your actions on MyActions.org. Add a connection to Cincinnati Zoo, and help us achieve our group goal.
