LOL.

As a point of reference, as I understand it, all mammals have receptors for capsaicin so it works on all of us.

Wild animals can do a lot of damage. A group of us got chased by a raccoon once. Nobody wanted to beat on it and we weren't in a rush so backing off was easy. It was pretty funny getting chased by an aggressive critter.

I once watched as a squirrel that was assumed to be dead woke up when the hunter picked it up. It started wiggling and ran up his arm. He was thrashing so much, and screaming like a girl, it was hard to tell who was doing what to who. It kind of looked like the squirrel ran around his head a couple of times. Big guy, better than 300 pounds and tall, a combat veteran, stymied by a squirrel. I near about hurt myself laughing. Took a considerable amount of snake-bite-remedy to take the edge off. The boy lost a lot of his enthusiasm for hunting tree rats.
