this probably has been discussed..but I'm in a bit of a rush today. Hammie hasn't eaten any grass...I am with him all the time..he goes out on a leash. When I've put him in the pen for a short time to play..or me wash the floors, etc., there is only gravel floor and some dirt. He is frisky...his usual goofy self..tons of energy..but I just took him out and he had a green stool??? We came back in and I fed them..he ate like normal. (actually...he is truly his silly self..LOL) Is this 'normal' sometimes????? you know I fret..... thanks!
