[matese]

My boy is older then your babies (he was 3.5 y/o) , but I went through this last year. For 18 months he was eating Natural Balance limited ingredient, it comes in a variety of dif. meats, kangaroo, rabbit, venison etc. every 4 months I would change to a dif.meat. Then one day he sniffs and walks away, next day the same thing, I sprinkled the Parmesan cheese on the food and he ate it.The next day I got him a dif. meat same thing,again sprinkle the Parmesan cheese, again he eats it. It's a good thing Pet Supplies takes back open bags lol. I too had the same transition situation. I purchased a bag of Welness Core to see if he would eat that, and yes he did, so what I did to transition him over was gave him the food he would ONLY eat with the Parmesan cheese sprinkled on it in one dish, when he finished that I gave him the wellness is a separate dish and transitioned him that way. This is what worked for me. Good luck.
