What Should Be the Ideal Weight for Cats?

 Ideal Weight for Cats

 There is no one-size-fits-all answer to this question because a cat’s ideal weight depends on many factors. It varies from various factors. Some of the factors that determine a cat’s ideal weight include the following:

  • Age
  • Breed
  • Gender
  • Activity level
  • Health status
  • Eating Habits


Considering your body weight is determined by your age, BMI also counts your age, and your BMI is determined accordingly, just like a cat’s weight is determined by its age. For calculating the BMI, the Feline BMI calculator is used. In this, there are some of the points that you need to remember. So here are the points to remember;

  • To check the BMI, you need to check the fat over the rib cage of your cat. The rib that is ideally checked is the 9th rib, i.e., the size of the rib cage at the level of the 9th rib.
  • For this, you must make your cat stand on its legs and then the head posture at the uppermost position.
  • Now you need to measure the ribcage at the level of the 9th rib cage.
  • Then after this, you need to calculate the length of the leg of your cat.
  • To calculate it, take the measuring tape and then measure the knee to the ankle of your cat.
  • After measuring these parameters, you will need to put them in the Feline BMI calculator.
  • Then the BMI of your cat will be calculated.
  • The formula, i.e., FBMI=0.91560.70622rib cage​−leg​−leg, is essential to calculate the BMI of your cat.
  • You can also use the online Feline BMI calculator available on various sites.

The ideal BMI of your cat must be between 15 – 29.99. Below 15 is considered underweight, and above 30 is considered overweight. If the BMI is above 42, then it is considered obese. And this is the point where your cat is considered at risk. Using the BMI calculator, you can set the value somewhat between 15 and 30 and then check what must be the ideal measurement of the ribcage at the 9th rib and also the length of its leg so that you can work on these parameters.


According to the breed of the cat, its weight is determined. According to the breed, cats and their physical condition are different. There are some breeds in which the ideal cats are lean, while the perfect cats are overweight in some species. So this parameter is also important to consider before assessing your cat’s weight and knowing how heavy should my cat be.


Like ideal cat weight is determined by gender, so in humans, a male weighs more than a female. The same rule applies to cat species. The ideal weight of the male cat is around 11 to 15 pounds, i.e., 4 to 6 kgs, and that of the ideal female is 8 to 12 pounds, i.e., around 3.5 to 5 kgs. So a female cat of 15 pounds is considered overweight and needs to intervene in the dietary habits. Also, a Male cat weight around 18 pounds is considered overweight.

Activity level

If the cat’s behavior is playful during the day or her activity level is too high, she may be underweight or overweight, depending on how active she is. Generally, cats are the least active as compared to other animals. But in the cats, too, some of these are much easier, and some are more active. So activity level of your cat will also be a determining factor of your cat’s weight. A sedentary lifestyle of your can and excessive eating of food can increase your cat’s weight, and it will confuse you to check how heavy should my cat be your cat should be. Also, being excessively active and not much interested in eating the food can hamper the health of your cat. So these are the parameters to access your cat’s weight.

A diet right in carbohydrates is harmful to the pet animal, especially the cat.

Generally, a healthy adult cat should weigh between 7 and 12 pounds. However, this can vary depending on the breed of the cat. For example, a Siamese cat is typically leaner and lighter than a Persian cat. Similarly, male cats are generally larger and heavier than female cats. The cat’s age is another factor that can affect its ideal weight. Kittens, for example, need to gain weight rapidly during their first few weeks of life. However, once they reach adulthood, they should maintain a stable weight. On the other hand, senior cats may need to gain or lose weight depending on their health status.

Activity level is another factor that can affect a cat’s weight. A cat that spends most of its time sleeping or lying around will require fewer calories than a more active cat. Similarly, spayed or neutered cats may have a lower metabolic rate and require fewer calories than intact cats.
