The Problem with “Average” Cat Weight

Resources that list average or normal cat weights may not consider all the factors that influence weight. Elements such as age, breed, sex, and whether a cat is spayed or neutered can significantly affect their weight.


For instance, the typical weight range for a Siamese Cat is between 8 and 15 pounds. Female Siamese cats usually weigh between 8 and 12 pounds, while males generally range from 11 to 15 pounds. Therefore, a 15-pound female Siamese would likely be considered overweight, while the same weight might be perfectly healthy for a male.

People often overlook mixed cat breeds since they are a blend of two unidentified cat breeds which makes it quite challenging to determine their average weight.

How much should a cat weigh?

The weight of cats can differ based on their breed; however a typical weight range for most is around 8 to 10 pounds (approximately 3 to 4 kilograms). Some larger breeds may weigh up to 25 pounds ( 11 kilograms) while smaller breeds can be as light as 5 pounds (approximately 2 kilograms). The average weight chart outlined below serves as a reference point, for the most common cat breeds.

Why is maintaining a healthy weight for a cat so important?

Obesity in cats, much like in humans, can lead to serious health problems. Overweight cats are at risk for conditions such as diabetes, pancreatitis (a painful condition often linked to a high-fat diet), arthritis and joint issues, feline skin cancer, and skin sores. Monitoring your cat's weight is crucial for maintaining their health and lowering the risk of these issues. It's important to ensure your cat maintains a healthy weight to support their immune system, energy levels, and overall well-being.


There are simple tests to determine if your cat is at an ideal weight. Start by assessing their body condition: Do they appear overweight or underweight? Does their belly sag, or do they look noticeably different from other domestic cats? If you're finding it difficult to judge because you see your cat every day, ask friends or family if they notice any changes in your cat's appearance. Running your hand along your cat's rib area can also help you assess their condition score; you should be able to feel their ribs without excess fat covering them.


Remember that a cats ideal weight may vary depending on its breed and health condition. Maintaining your cats fitness requires providing them with a diet in protein from quality cat food. Consult a weight chart to assess your cats weight compared to the weight for their breed. Keep in mind that whether your cat is, on the end of the spectrum can significantly impact their overall health and happiness.

Other tests can include

When you pet your cats side with your fingers can you easily feel their ribs under your touch or sense their spine without effort. Do you notice their shoulder bones protruding? If you answer yes to any of these then it's likely that your cat is, at a healthy weight Alternatively if the ribs spine and shoulder bones are noticeably prominent your cat could be underweight.


If it's hard for you to feel your cats bones or see a bit of fat over them when you touch gently with your fingertips on its sides or back areas that could mean your cat is carrying some weight around its midsection. To help maintain a weight for your feline friend and keep it healthy in the long run it's important to regularly check its body condition and ensure it stays within the recommended range. Feeding your cat a diet that is high in protein will play a role in helping it maintain a healthy weight and enjoy overall well being. Remember that the ideal weight for cats can differ based on their characteristics; therefore using a body condition chart can be helpful in assessing whether your cat is, at an optimal weight level. Ensuring that your cat stays at the weight is essential, for keeping their immune system strong and promoting their overall health and happiness – regardless of whether they are overweight or underweight.

What if My Cat is Underweight?

Obesity is a concern for many cat breeds, but some cats can also be underweight, particularly if you've recently adopted a cat or taken in a stray.


If your cat’s Body Condition Score (BCS) suggests they’re too thin, your veterinarian may recommend increasing their food intake or suggesting a higher-calorie cat food to help them gain weight. “It’s also a good idea to measure the amount of food you’re providing,” says Dr. Lobos. Additionally, blood work might be recommended, especially if your cat has suddenly lost weight or exhibited behavioral changes like increased drinking or urination. Once they reach an ideal weight, an adult maintenance formula can help them maintain it long-term.


While it might be tempting to give your underweight cat extra calories from any source, it’s important to avoid overloading them with treats. Treats can lack the essential nutrients your cat needs and may cause them to gain excess fat. Overindulgence could also disrupt the balance of necessary nutrients, such as vitamins and minerals, in your cat’s diet.


Don’t forget the importance of exercise and activities. These are crucial for helping your cat build muscle, which will aid in healthy weight gain.

How do I get an obese or overweight cat down to a healthy cat weight?

Reduce the number of treats you give your cat and avoid feeding them any human foods. Ensure your cat is on the right diet for their life stage. For example, a neutered or senior cat may benefit from a diet designed for better calorie control. If your cat is overweight or obese, consult your vet or a registered veterinary nurse about specialized weight loss diets. These diets offer all the necessary proteins, vitamins, and minerals while lowering calorie intake. When switching to a new diet, remember to introduce the new food gradually over a week.

Exercise and enrichment are important too

Using puzzle feeders is also beneficial for cats! It's like giving them a hunting challenge, for their food instead of just handing it to them on a plate. Kind of mimicking their natural instincts in the wild while keeping them mentally stimulated and active by burning calories. see below a list of the best puzzle feeders on the market, that are proven to aid weight loss.
