NASCAR pet lovers can now help support the Humane Society of Iredell County while showcasing their Killer pride with the purchase of a fashionable t-shirt or hat that have all the personality and spunk of the real Killer, just without the slobber. A portion of all the proceeds from the Killer t-shirt and hat sales will go to the Humane Society of Iredell County so they can continue to help support less fortunate animals.
