About The Cougar Fund

The Cougar Fund is a non-profit organization based in Jackson, WY, working to increase knowledge and tolerance of large carnivores through education and outreach. Although our work is focused on wildlife, we believe that all aspects of a healthy environment and habitat are essential for their survival, and therefore offer a wide variety of programs on various ecological subjects.

Who We offer hands on programs and activities to children of any age, in groups of 5- 25 students.
What The Cougar Fund engages students in wildlife and habitat focused games and activities.
When We are available year round.
Where Different activities will be suitable to different locations, including outdoors, classrooms, large indoor spaces (like the gym). We can tailor the program to the space you have.
Why At The Cougar Fund we aim to put the WOW into WILDLIFE! Children are inherently attracted to animals and we take advantage of that curiosity by teaching them all about their environment and habitat using hands-on activities and games. By learning to love wildlife, we hope that in the future those same children will want to protect and preserve them, as well as the sensitive places that wildlife call home.
