Check out this great trail cam clip of one young mountain lion teasing another after it was captured in a live trap. The clip comes from researchers with the Santa Cruz Puma Project, who set the trap to catch lions and fit them with radio collars.

According to the project’s blog, the trapped lion was a 14-month-old male. Researchers named the cat “41M.”

“While we collared him, we could see the eye-shine of his mom or sibling watching us from a short distance away. We weren’t able to catch anyone else that night, but we did get this fun video of 41M playing with his sibling through the trap (who is no doubt laughing at him, as I know my siblings would do).”
