C&S Suet Treats are produced by melting the highest quality beef kidney fat, blending a variety of seeds, nuts, and fruits that are then poured into a tray and allowed to harden. Our Suet Treats will become soft and pliable at 100° F if exposed to extreme heat during shipping and storage, but will return to normal hardness again at room temperature. C&S’s quality and special processes allow our wild bird suet to be fed year round resulting in all season suet feeding success by our consumers.
