apparently one of the kittens pulled a feather off of one of the feathered toys, and Niki found it. Unfortunately I didn't get any photos of her trying to 'kill' it. Mostly because I was laughing too hard as I was pretty sure for most of the 'kill' the feather was winning. She stood up on her hind legs trying to shake the feather into submission and fell over several times. It was a riot.
Then one of her sisters decided that the feather must be an awesome toy and tried to steal it. Niki got very possessive and grabbed it in her mouth and ran across the room and tried to evade the thief. These kittens are very big on parkour and watching them run side ways on things in chase almost made me fall over from laughter. Finally they gave up and Niki was able to enjoy her prize. I let her play with it while I watched then took it away from her when interest started to wain.
