I just gave this product to my cat yesterdy, and took him to the vet today. My cat began flipping his back feet continually after using this product and not eating much. When i asked my vet about this product she said it was not good at all to use on cats. She recommended frontline or revolution. So, i am throwing away the other two applications. I'd skip this product.
