Are you going straight from dry to raw?
I am not familiar with that raw brand, but I do know most recommend NO kibble/dry when raw feeding. Generally you transition to wet (canned) food first, then to raw.
While transitioning, you could boil/bake chicken for your cats. Just chicken, nothing else...no spices, oils, nothing. Cut into small chunks...NO bones, and use it as a "treat".
