I wanted to get my cards organized for easy expansion sorting and game play. This all fits in the Barking Kittens box, and holds all current expansions (Imploding, Barking, Streaking, and a few promo cards) with room to spare. I personally use Dragon Shield Clear Red Matte card sleeves for this game (it hides the slightly different shades or red in the expansion card backs, but lets the logo shine through), so it is designed to fit those sleeves.

The deck holder tray is great for containing a draw and discard pile during game play.

Note that the instructions for Barking Kittens were not folded the same way as the others, so I had to refold the instruction sheet for it to store in the slot with the others. There's plenty of room to store instructions on top though if you didn't want to do that.

If you aren't able to print it yourself you can grab it from me on Etsy: https://www.etsy.com/ThreeStripeFrogs/listing/1211478438/component-tray-organizer-insert
