Steve's Real Food for Pets is a freeze-dried, wholesome, delicious, nutritious, raw meat, fruit and vegetable-based food for pets. The freeze-dried versions are identical (with the exception of moisture content) to Steve's frozen diets and can be served as a complete and balanced meal. They're also much easier to transport. All packages have an unopened shelf-life of over a year. After opening, if the product is placed in a sealed container in a refrigerator it will last for up to two weeks, and up to a month if kept in a freezer.
