Working together

 All of the kitties were very interested in the new "foe" that needed to be taught a lesson.  Each one took their turn "killing" this new "enemy"  I haven't seen them all enjoy a "toy" together since the last time I brought out the feather string toy.

Can you guess what this might be?

Apparently the top of the box of small cans of cat food (think store brand version of Fancy Feast) REALLY needed to be taught a lesson, and Kif thought he was just the kitten to do it.
