I didn't realize you had been testing after feeding Panic for pre-shots. If you must give her food to get her to co-operate, use the food as a bribe. Give her a small bit, test and then give the rest as a treat for her co-operation. You're probably Ok if you are testing immediately when Panic finishes eating but better to grab the test before if possible. I take it the "food machine" has a timer and doesn't allow snacking in the 2 hours prior to AMPS?
