At the end of every summer, the exotic cats who reside at Florida’s Big Cat Rescue go into battle against some unusual critters that show up in their enclosures.

The creatures are all kinds of different colors, and they’re made out of a combination of boxes and papier-mâché. They’re the work of the rescue’s summer campers, and they provide quite a bit of entertainment for the tigers, jaguars, cougars and more!

Watch as the big cats tear into their “prey,” in the video below.
