C&S Products 11 oz. Peanut Treat Suet Cake is blended to attract a select group of insect and grub feeding birds year-round. Made with rendered beef suet, roasted peanuts, oats, corn, and milk, this suet cake provides a concentrated source of energy for wild birds. Designed for use with suet cake feeders, it becomes soft and pliable at 100 degrees Fahrenheit but returns to normal hardness at room temperature. Refrigerate for easy removal from the package and insert into the feeder. Attracts a variety of birds including blackbirds, bluebirds, cardinals, chickadees, crows, doves, finches, flickers, goldfinches, grackles, jays, juncos, mockingbirds, nuthatches, siskins, starlings, titmice, woodpeckers, and wrens.
