I was feeding my cat Science Diet dry, but given Hill's involvement with Menu and its recall of m/d, I decided to try Felidae and see if my cat likes it. I noticed that the food (the regular dry formula for cats and kittens) has little white specks in the food that look like salt. I assume it must be one of the ingredients, but since I've never seen that before in dry food I wanted to check with those of you who have fed Felidae before. Is that normal?
