A 35 pound cat of any species could **** you up.
What was the guy supposed to do, distract it with a laser pointer?
Only if you allowed it to. In the post above yours I gave the physical size of my 22 pound cat. Sorry, he's no threat but to baby rabbits. From the size I've given you should be able to see how small a cat would be who is 10 pounds heavier.
And no, it would be no serious threat. I would have helped the starving animal.
And you would have died.
Yes, your housecat is not a threat. Being well fed, I assume, it has fat on it as part of that 22 lbs. This was a wild predator that was starving. It would have fought until it died.
I once saw a raccoon that weighed no more than 20 lbs kill a full grown german shepherd.
Also, the man said the cat was latched onto his wrist and clawing at his face and neck. Your housecat would be lucky to reach your elbow with its front paws if it latched on to your wrist. The young cougar would have much longer legs. Those claws could slice deep enough to sever your carotid artery or jugular vein, and you would have died on that mountain.
This idea that there was no threat shows your ignorance of wild predators. I work occasionally helping a guy who uses goats to clear overgrown land. He lost a large buck to a bobcat several years ago. The buck weight 175lbs or more, but it was still not enough to fend off the bobcat. And bobcats rarely weigh 40 lbs. He uses Great Pyrenees to protect the goats. No he has 2 er herd, in case one gets sick and has to be taken to the vet.
