I've eaten cougar.
Years ago, in St. Maries, Idaho, they used to have a wild game feed to benefit Hospice. Folks would bring all kinds of wild game to the Eagles Aerie, and the Ladies of the Eagles would cook it. Or it was prepared before the event by the contributors.
One year, a woman showed up with a BIG crock pot full of cubed cougar meat in barbecue sauce.
The consistency and flavor was like pork. If you didn't know, you'd have thought it was cubed pork. Wonderful eating, with a good, pork-like flavor. Very lean, with no trace of fat.
I'm a cat-lover, so it took a bit to get past that first bite but I'm glad I tried it.
An earlier post warned of trichinosis, and rabbits carrying that organism. Rabbits carry the tularensis organism but, I don't believe they carry the parasite that causes trichiniosis. Pigs carry trichinosis. Be warned: Any undercooked meat can cause sickness, even death. Make sure you cook everything -- wild and domestic -- thoroughly.
