Though a chubby cat may look cute, feline obesity is a significant problem that’s extremely dangerous to a cat’s well being. It’s estimated that about 40% of adult cats are obese and indoor cats are more prone to obesity due to their sedentary lifestyle. As with humans, diet, lack of exercise and genetics can impact a cat’s weight. Also like humans, overweight cats can suffer from heart disease, diabetes, high blood pressure and arthritis. It’s important to figure out the reason your cat is gaining weight if you want to help them lose it in a safe and healthy manner.
