Recently, we saw a rabbit in our back yard on one occasion and a feral tabby cat on another day doing what they do best.
The cat was hunting and the rabbit was on the lookout for hunters. The hunted and the hunter are both alike in many ways except for the most obvious—one gets to eat the other.
Otherwise, in action they are both like coiled springs: alert, jumpy, and ready to do what they do best, flee or pounce.
Whether you are predator or prey, you do this every day.
