Cat’s Body Weight Classifications

We’ve classified your cat’s body weight into several classifications to assist you in determining whether or not your cat is unhealthy.

Extremely Underweight 

Underweight cats needed immediate care. It is uncommon to spot a feline in this state unless it is a stray or neglected by its owner. Cats who are very malnourished will have visible ribs that may be seen from the side as well as from above when you are looking at them. The vertebrae across the tail will be exposed and more noticeable than average. The stomach tuck will be severe, and they will typically have lesser energy left for hunting or playtime. A feral cat will forget its dread of people and move ahead to seek some food.


Underweight cats will have a little fat on their body and not substantially more than that. You will still recognize the ribs from its side, and it will be straightforward to sense when you touch the feline, but looking at them from above may be more challenging. Even though they are underweight and in desperate need of nourishment, they will have enough stamina to hunt and play, and they may even prefer to hide or flee from people if they are challenged. When there are many feral cats, mainly when it is wintertime, most of them are malnourished.


While petting a cat that is at its optimum weight, you will be able to feel its ribs without exerting any effort, but they will not be visible until the cat is stretched, leaping, or scrambling. Upon gazing down on the cat from above, the tail vertebrae will be covered, but they will be shaped and apparent, forming a cats’ waist. The cat’s hair will be glossy, and it will be engaged and productive during the whole day. Pet parents must put in the most outstanding effort to keep their cats in this weight bracket for them to live the healthiest.


Overweight cats are easily found in many households throughout the United States, outstripping average weight, and have become a significant problem. Although you will still be able to touch the ribs of an overweight cat, pressing on them will be difficult, and you will also feel their fat. You will notice that the tail vertebrae are nicely buffered and that the body bumps somewhat towards the rear with no discernible waistline.


Obese cats, like extremely underweight cats, need urgent medical care. These cats are at risk for various health problems, such as cardiovascular disease, obesity, renal illness, and other ailments, which will reduce their lifespan. The excess weight will also put a strain on your cat’s joints, making it difficult for it to climb and leap as it would otherwise. It makes it challenging for the cat to inflate its lungs, making it harder for them to breathe. You may also observe the feline snoring more frequently as an effect of the excess weight. On such an obese cat, it will be tough to feel the ribs, and there will be no evident waistline, and the back end of your cat’s body will flare out.

Factors Affect Your Cat’s Body Weight

When it comes to cats, weight growth may occur gradually over time, so it’s essential to keep track of your cat’s weight now and then. A healthy feline will weigh approximately 8 and 10 pounds on average. Although there are several variables to consider when calculating the proper weight for a cat, the following are the most important to look out for:

Health Status

A major factor will be the overall health of your feline. Cats are susceptible to various underlying health issues, any of which may result in losing weight or gain. The signs of an overweight or obese cat are pretty obvious to detect, and your veterinarian may evaluate their overall health score. To determine whether or not they’ve been gaining pounds by considering their height, weight, and quantity of body fat they have on their frame. As a general rule, your feline will be deemed overweight if their overall fat percentage is more than 25% and obese if it exceeds 30% of their body mass.


Since there are numerous breeds of cats such as Siamese, American shorthair, sphynx, and others that vary in size and various other characteristics directly related to it. Genetics is also essential since male cats are typically larger and weigh more, while female cats are smaller and weigh less.

In general, larger breeds weigh more than smaller ones. For instance, a Siamese cat weighs roughly five pounds, while a Maine Coon cat weighs approximately twenty pounds. A ten-pound Maine coon is considered a healthy feline, while a ten-pound Bambino cat is deemed obese.


The gender of the feline also affects the weight of the cat. Male cats are usually bigger than female cats, particularly if they have not been spayed before sexually mature. Male cats are often heavier than female cats, although the discrepancy is not significant. A female cat typically weighs between 8 and 12 pounds. Male cats, by contrast, weigh between 11 and 15 pounds. Thus, a female cat weighing 15 pounds may be deemed overweight, while a male cat weighing 15 pounds is normal.


Cats of various ages may weigh differently. Generally, a maturing kitten is taller and thinner, while a neutered matured cat is bulkier and hefty. As feline mature, they often lose muscle mass and fats, resulting in a loss in weight.

Age is particularly vital since cats’ bodies experience many changes as they mature, which results in a gain in weight for many cats. Nevertheless, routine veterinarian examinations are necessary to detect any changes in your cat’s body weight. 

Additionally, the standard weight of a feline is determined by its age. For comparison, a mature female Maine coon cat may weigh up to twenty pounds, while a mature Himalayan cat weighs just seven pounds.

The four most popular breeds, the Siamese, Maine coon, Persian, and Himalayan, achieve their mean peak weight between six and ten years of age.

Why Does Weight Matter for Cat?

Whenever your cat is lingering around the treat container, it is simple to throw them some more treats. However, an excess of calories may build up to extra pounds over time, putting the body under additional strain. Overweight cats are at an increased threat of developing diabetes, rheumatoid arthritis, as well as skin and joint issues.

Obesity is a frequent issue with cats since it’s not always easy to determine what your cat is consuming or how much activity they’re receiving when permitted to wander freely outside. It’s something you should keep an eye out for since it may have a variety of undesirable effects if allowed to spiral out of control.

Excessive fat from weight gain may have a detrimental impact on your cat’s wellbeing. Felines are inherently active animals, and as they gain weight and lose their flexibility, they are prone to experience anxiety and depression. A balanced diet combined with various friendly activities may ensure your furry companion enjoys the healthy, comfortable lifestyle they need.

What to Do If Your Cat Is Overweight

Avoid foods containing maize or soya. Provide your cat with three or four moderate meals during the day rather than the food they demand. 

Increase the amount of time you invest interacting with your cats every day to encourage them to be more energetic. It is also recommended that you consult your veterinarian for guidance.

What to Do If Your Cat Is Underweight?

If your feline is underweight, you may increase the amount of nourishment you give them. Cats are voracious eaters, so if your it is noticeably underweight while receiving enough nutrition, it may be a symptom of a medical problem that requires treatment from a veterinarian. Dental issues, intestinal worms, obesity, thyroid, and even poor-quality food may all be contributing factors to your cat’s sudden weight loss.
