If you’ve ever had a kitten, you know they like to climb on practically everything. If you happen to be wearing a pair of jeans, your legs may look just like two trees to a kitten’s eyes.

That’s exactly what happened to one woman surrounded by curious kittens. The kittens keep climbing and the woman keeps laughing. Even after the woman peels the kittens off her legs and plops them back on the ground again, they pop up once more for another chance. If that’s not determination, then you’d be hard pressed to find what is.
