Pampers new formula make cats sick

My cats loved the original Friskies formula, but you changed it, and sell the product as if it never changed. My cats refuse to eat the food, and they lost weight drastically. I changed to whiskas, but one of my cats struggles to eat that now as well. My friend gave her cat pampers as well, and it gave her kitty heavy diarrhea. I lost all faith in this brand, and hope to see it discontinue from the market once and for all.
