A female British Shorthair cat can grow to about 8-10 pounds after 2 years. The weight of a female cat after pregnancy will increase by 1-2 pounds on the original basis. Generally, the growth period of British Shorthair cats will stop when they are 2-3 years old. When the British Shorthair female cat is underweight, attention should be paid to supplementing food with higher nutritional value. When the weight is overweight, the cat should be given more exercise. It is best to maintain the adult female cat at about 8 pounds.

The weight of British Shorthair cats is related to nutritional structure, physique, and sterilization. British shorthair cats with weak physique, malnutrition, and unneutered cats are generally underweight; those with good physique, comprehensive nutrition, and good appetite will weigh more after sterilization. You can roughly judge whether the British Shorthair cat's weight is up to standard by touching its back bones. If you can feel the bones that are obviously abrupt, it means that you need to strengthen nutrition.

If the cat’s weight exceeds the standard range, it is necessary to feed less food with higher fat content and increase protein food appropriately to maintain the cat’s health.
