If you’re concerned about your American Shorthair’s weight then you should give your vet a call and take her in for an exam. Your vet can weigh your cat and tell you if the cat’s weight is on average, below average or above average. Keeping a journal of what your cat eats for meals and snacks as well as the amount of exercise your cat receives can also help determine areas that need improvement for your cat’s health. You can also check your cat’s weight at home by weighing her on a scale. In addition, your vet make recommend a quick home check where if you can easily see or feel your cat’s rib bones then she is too then. If you feel a layer of fat covering the rib bones then she may be overweight. This is not to be used as a professional analysis, however. Always call your veterinarian Columbia, MD for professional advice.
