We recommend using our product within 2-3 days of thawing in the refrigerator for freshness. If you have a smaller pet, you can thaw our 1 lb pack for 8-18 hours until it's slightly frozen but still soft enough to cut, then re-portion and re-freeze in smaller tupperware or in an ice cube tray. *Note that thawing times can vary depending on the recipe, the temperature of your fridge, and where the product is placed. For quicker thawing, place the product on a shelf where there's better airflow rather than in a drawer.
