In our refrigerated kitchen, RAW human grade proteins, fruits, vegetables, vitamins, minerals and natural preservatives are blended into our dog and cat food and topper recipes. Still frozen, they are then placed into our freeze drying chamber. Once in the chamber, temperatures are brought down even further, and ice is gently removed from our recipes through sublimation in a vacuum. This method forces the ice to transition into vapor and water is gently drawn out of our food • toppers. From start to finish, our freeze drying process can take up to 24 hours to complete. Once complete, delicious morsels of RAW freeze dried goodness are removed from our chamber and placed into our bags for your pets to enjoy. Our freeze dried food • topper recipes have all the aroma, texture, nutrients, and freshness locked in that dogs and cats crave and pet parents love.
