Thanks for all of the great ideas! Until reading this, I have only thrown scratch or thrown out flakes of straw. They love to scratch around in straw and that will typically keep them occupied for days. It is fun to watch them the first few minutes play king of the mountain with the straw. I am definately going to try the gatorade bottle with grains and BOSS. BTW, thanks for the explaination, I did not know what BOSS was either....
