This product is worth any problems I had getting him to eat it and there were many problems until my 'cat-whisperer' urged me to mix a serving of the Phyto Synergy with a tablespoon or so of his food, add a little water and let the ingredients marinate in the frig. It took 24 hour marinades at first, and then I would mix that in with his food, and then he would eat it. After some 'training' and experimenting I got it down to a 8 hour marinade. If you have the fortune to have a very stubborn little person, please don't give up on them.... they may be more stubborn, but we are more cunning. Good Luck.
