I have always been scared to death of thunderstorms but Mom and Dad found Canna-Pet and I don’t hide from the noise any more! This stuff REALLY works! I would also like to add so that you will know how much of a problem this is for Maddie…. we live in Florida. During the rainy season which may last up to two months it can thunderstorm every day at least once sometimes twice. We have tried everything and the answer was always there. We are so happy with the results of this product and the customer service and helpfulness as well. Thank you again… Sue Robert and Maddie Mitchell
