My grandma had a cougar that she nursed back to health and kept in a cage under the outside stairs leading up to her house. it took a long time to get the cougar nurse back to health. She'd open the cage every night at dusk and eventually the cougar started to go out and hunt and be back in the cage every morning, then she'd close the cage. She never had it as an indoor pet though and she lived out in the country letting the cougar out into its natural habitat every night.
Look at these Russians with a pet cougar!
What the fuck are you stupid Russians thinking?
