Hi Eric, it sounds like your on the right track, and I hope the transition continues to go well. The best way to do a slow food transition is over 2 to 2 1/2 weeks. It can take up to a month to see any improvements, as it can take that long for the old food to leave their systems. Keep up the good work, and I hope the new food gives successful results, and Ace tolerates it well. Good job Dad.
