Is feeding raw something which must be done every meal to see the benefits? Does feeding raw as a treat once a week still benefit the cat? I'm sceptical about the precautions and time needed to feed raw and am looking for the next best thing to a raw diet. I was looking at the package of FreshPet Vital Grain Free at Petco today and am considering looking into it further. It does seem really pricey though. Can the Primal pet foods freeze dried nuggets really be left out dry for grazing? It seems like the prepackaged raw food is pretty expensive too.
