Getting Enough Minerals in Your Diet?

Appar ently Max wasn't because he attacked my poor defenseless seedlings. I put him by the window to enjoy the sun and when I turned back around he had a mouthful of dirt and like a good mother I picked up my camera and snapped a few shots before scooping fingersfull of it out. Needless to say he's been extra gassy and fussy for the past couple days. I guess mud doesn't go down as smooth as you'd think.
