I do the same...defrost a few for a couple days and keep in Tupperware and feed in PM. I do the NV kibble Prairie in the AM. The NV Instinct was too high protein for Cosmo as it made him drink tons of water and pee constantly (he is only 6 months old now and in potty training mode).
Our vet said switch to lower protein and I loved the NV so much and switched to the Prairie which is also a perfect rotation diet too. Since switching to lower protein Cosmo has been not drinking as much water.
His teeth and coat look amazing.
I'm very happy with the NV.
Oh NV medallions are lower in protein Primal that's why I'm sticking with the NV.
