Animals do things we'd never imagine them doing. I've seen a few such.

A deer, playing with my cat (cat didn't know what to make of the situation)

My cat, running off a bear who'd strolled by her and her kittens.

A buck deer, slowly stalking a fox, which circled around behind the deer in a small grove of trees and was then behind the still-stalking deer. Absolutely comical.

A strange parade of a deer, being followed by a fox, being chased by a dog, with about 60 feet between each participant, moving like a freight train they were all running so fast.
