The real test is going to be tomorrow morning around dawn when he gets feisty and starts looking for things to shred.While the front end of the bed was still open this morning, he went under there and started attacking the inside of the cardboard on my side of the bed with INTENSE CONCENTRATION - it took a lot of noisily shaking his breakfast pellets to get his attention.So we'll see if he finds an angle of attack 'round sunrise.
