It tells on alot of flea med boxes which one to use based on your cats weight. Regardless, 25 pounds is too much for a cat to weigh. You really need to buy light, weight management or however it may be written, cat food for this cat & make sure he/she gets plenty of exercise. Try using a laser pointer or even a flashlight to make your cat run around.
