There may be many reasons why cats gain weight, including diet, exercise, genes and health conditions. Diet is a major factor. Cats may gain weight if they eat foods that are heavy or high in fat. Cats may also gain weight if they are overfed or eat inappropriate foods.
The amount of exercise is also a factor. If cats don't get enough exercise, they may gain weight. Cats love to play, so they need plenty of opportunities to exercise. Genes may also be a factor. Certain breeds of cats are more likely to gain weight than others. Medical conditions can also cause cats to gain weight. Some conditions, such as hypothyroidism or diabetes, can cause cats to gain weight. If your cat is gaining weight, it's best to consult with your veterinarian to determine the cause and develop a treatment plan accordingly.
