but to answer. don't you think a leopard would kill a wolf? there are actually pictures of a leopard who has battled down a quite big hyena.
a single hyena is a much harder apponent than a lone wolf,

Cougar need to step it up.

 

Its pretty  much a fact that Cougars  have killed bears and wolves a lot more than leopards kill other predators around the same size. If you look in one of the earlier pages of edge of extinction, you read a brief description of the Leopard being less confrontational than a Tiger.


This lion doesn’t run, instead kills, eats wolf
Wild-eyed research cat stripped lobo to the bone, researcher says.

Five mountain lion cubs mothered by Teton Cougar Project research animals have met their ends in the jaws of wolves over the past few years.
Now a Jackson Hole female cougar appears to have exacted vengeance.
A lion tracked by the Kelly-based science institute for the past six years is documented to have recently dined on a yearling wolf, Cougar Project biologist Mark Elbroch says.
“What’s nice about this particular incident is that this is a collared mountain lion, and we know for sure that she killed it,” Elbroch said. “This is just a very nice, clear case.”
The wolf-killer, known as F109, is a 101-pound female that lives in the Gros Ventre River headwaters. She’s a “funky-looking, overly feral cat” that’s as smart as they come and near impossible to catch, Elbroch said.
While hiking with colleagues early last month, Elbroch discovered the cached remains of the young wolf while on a routine visit to check a suspected F109 kill site.

A bloody scene, and a surprise
After a 2 1/2-hour uphill hike through snow, the team of biologists came across an ominous sign, Elbroch said.
“There were wolf tracks everywhere,” he said. “Not just one wolf, but a full pack with pups and subadults.
“I was thinking, ‘Oh gosh, this is not good,’ because she had kittens at the time that were small and defenseless,” Elbroch said.
The biologists saw lion tracks, then blood, then a jet black pelt at the base of a subalpine fir tree.
Though dead only a day, the wolf was nearly consumed, Elbroch said.
“You don’t expect it to be a wolf,” Elbroch said. “The one really intact part of the carcass was the skull.
“We were able to clean it off, and there’s no denying what it was,” he said. “It was a wolf born this year.”
That meant the wolf pup was already larger than a normal-size coyote.
While not unheard of, proven cases of lions killing wolves are far from normal, scientific literature shows. Wolves killing lions — evidenced by the Cougar Project’s experiences — is much more common.
Through 2008 there were three reports of cougars killing wolves in North America, Jackson Hole resident and biologist Mike Jimenez wrote in a short entry to The Canadian Field-Naturalist. One of the unlucky lobos was one of the original Yellowstone imports — Wolf B-4.

Top dog sometimes loses
In early 1996, B-4’s radio collar was detected sending out a mortality signal near Drummond, Mont.
In 2003 a cougar-killed female wolf was found in Paradise Valley north of Gardiner, Mont. In 2006 a healthy male wolf killed by a lion was found in Alberta’s Turner Valley.
More recently, in early 2012, a Montana Fish, Wildlife and Parks wolf biologist reported that two of her radio-collared wolves had turned up dead with trauma consistent with a lion attack.
It’s much more common for wolves, a pack animal, to force lions to flee when the two large carnivores cross paths, Elbroch said. Typically, he said, the wolves chase off the lions.
“The scientific conclusion out there is that they interact as competitors,” he said. “Neither one is trying to catch the other as a prey source.”
That F109 and cubs consumed the wolf pup is a case of “interguild predation,” Elbroch said.
Only on one occasion — a fox — has a Teton Cougar Project research animal been documented making a kill and leaving the meat untouched, he said.
Because there was no video, Elbroch isn’t speculating about the encounter between F109 and the wolf pack.
“Perhaps the wolves had challenged F109, or perhaps just one of them wandered too close to her kittens, or perhaps a pup felt like exploring on its own — trying to decipher the absolute pandemonium of tracks was beyond us,” he wrote in a recent NationalGeographic.com blog post.
If the young wolf had wandered from the pack, maybe it appeared an easy meal. Elbroch said mountain lions are opportunistic killers, and they typically are not choosy about prey.
“If it’s a single wolf and everything’s perfect, why not?” he said.

"Here is your Monday morning video. In this one F109 visits a kill site from F61. The main feature of this clip is near the end when F109 performs a scrape with her hind feet. Cougars scrape to communicate their presence, breeding status, fitness/dominance and more. It is a fascinating behavior that deserves further study. F109 by the way is an impressive cat - she only weighs 88 pounds and hunts ~600 pound bull elk. She is also the only cat in our study to ever kill a wolf." Reply
