I bought sergeants gold squeeze for cats and kittens over 5 lbs. I used it properly and within minutes my cats reacted in a way that scared me so much that I stayed up with them practically all night. They had what seemed like nerve damage to their rear quarters. They began to breath very heavily and just act strange in general. Example, laying lethargically in places they never go to and seemed to be very sickly. I cannot believe that Sergeants can continue to sell this dangerous product. Please contact the stores you purchase this product from and warn them as to what this can do to your animal.
