I only have one guy that must eat live. I wish he would take p/k because I worry everytime I feed him. I know its what they do, and he is capable of handling himself, but still, I am a mom and worry. All my others get p/k. I don't have room in my freezer for f/t. So p/k vs f/t works better for me. No time spent thawing, no space taken up in freezer.
