So, why is your cat overweight?
Diet and exercise:
If your cat has gained weight, it’s likely they are eating too much or moving about too little. ‘Eat less, move more’ – this simple formula really does work.
It’s rare for a medical problem to cause weight gain in cats. However, if your cat has an illness such as heart disease, lung disease or arthritis they may gain weight because they aren’t able to exercise. If you have a female cat that hasn’t been spayed, it’s important to rule out pregnancy.
