I took a cougar a few years ago with my longbow. I should have got one spot and stalk last year but I missed. lol.

Darn I thought this would have pic's of some hot women in their 40's with bows

Never seen a cougar killed animal in a tree - or heard of anyone who has.  They cover up their kill as soon as possible after dragging it to a safe location.

A few years back I surprised a cat while walking back to camp at dusk.  All I had to do was release my arrow to get it while it was growling at me 12 feet away.         But it was a female with a yearling cub so I didn't shoot.  Next day I went back and found a cow elk she had killed - buried under some brush.  I took the cows jaw bone to remind me of the event.  

Cougars won't put a dent in a coyote population, but wolfs sure will.

Though it may be rare. I have seen a lion with my own eyes take a white fawn up a cotton wood tree and put it in a V.

Use a calf elk call

Lots of coyotes all over cougar territory and they don't drag deer into trees.

If any one is interested in trying to call one up I have a friend that makes calls and a CD explaining how to call them. If anyone is interested just PM me and I'll give them the information. He has called in cats using this method.

And yes, they are great eating. Just about the best meat that comes out of the woods.
