White meat lacks sufficient amount of taurine for cats. Legs and thighs and hearts contain a lot of taurine. Best to use thigh and leg meat.I usually do the chicken breast boil
Both the dogs and cats need calcium which they won't get if you aren't giving them edible raw bone or a calcium supplement. I usually recommend Mazuri for slab meat if you aren't feeding bone http://www.mazuri.com/MazuriCarnivoreSupplementforSlabMeat.aspx
