Lynx

While I don't like to see wild animals in captivity I will admit I didn't read the story and I just sat and watched a person pet a cat for 3 minutes.

Cats are smart, not for the normal reasons, simply because they learned that to purr for humans would trigger some sort of stupid response and either the human will do what the person in the video did or will ignore the cat completely.

Either is exactly what the cat wants.  Pet me or leave me alone.
