How Much Should My Cat Weigh?

A common question asked by pet parents is “how much should my cat weigh?” As a caring owner you want the very best for your furry friend, and that includes making sure she’s well fed.

However, unless you know what to look for it can be hard to tell if your kitty is the right size. In this post you’ll find out if your kitty is an ideal weight or not

Plus, steps you can take if your cat is either over or underweight. Also, common health problems related to weight and what you need to do.

What is the average weight of a cat?

Unless you have a large breed, most domestic cats weigh around 10 pounds. A Maine Coon on the other hand can weigh up to 25 pounds, and you can expect a Ragdoll to weigh between 15-20 pounds.

Oriental cats tend to be slim and lean looking, though males are often heavier. As a result, their looks can be misleading. If you have a female Siamese her weight should be around 8-12 pounds. On the other hand, males typically weigh up to 15 pounds.

Whatever breed of cat you have, males are always bigger in size than females. In addition, it should be noted that neutered tom cats tend to gain weight. This is because neutering is believed to slow down a cat’s metabolism by 20%!

How can you tell if your cat’s weight is ok?

weighing a cat

Obviously, if your cat is looking more like a barrel than a lean mean hunter, something is wrong! If you can’t see your cat’s waist she’s overweight. A good idea is to run your hand along the side of your cat. Feel for the ribs, and if you think they’re covered with a layer of fat, your kitty could be overweight.

On the other hand if your cat’s ribs feel prominent she may be underweight. This doesn’t necessarily mean she’s not eating enough though.

There are many reasons why cats lose or gain weight. However, feeding your cat too much is one of the commonest causes of obesity.

Getting your cat’s health checked annually by a vet is a good idea. Not only can it reveal any early signs of disease, but show if your cat is over or underweight.

Your vet will be able to advise you on your cat’s ideal weight and offer advice on feeding. This is a good time to chat about any concerns you have and if your feline friend requires a special diet.

Weighing your cat at home is possible, but you’d need to get scales especially for small animals. I’d only advise this if you’re really concerned about your cat’s weight, or if your vet suggests it.

BYKAZATY pet scale is multi-functional and comes with a tape measure. You may find this useful if you want accurate digital readings.

Your cat’s body condition score

Just as people use body mass index or BMI for evaluating weight, our pets have their own version. This is known as the body condition score with 1 being severely underweight and 9 being obese. The following video demonstrates how this works.

What to if your cat is overweight

A cat is considered obese if it’s 20% over the ideal weight. Just like with people, eating more calories than is burned soon leads to weight gain.

The first thing you need to do is look at your cat’s diet. This is because some brands of cat food are higher in calories than others. It’s not always the amount of food you give your cat that’s the cause of weight gain.

Talking to your vet can help as he or she will be able to recommend a specific diet. It’s important to follow any guidance given, and monitor your cat’s weight regularly.

If your cat spends most of her time indoors you need to get her active. Interactive toys your cat can play with on her own are great for stimulating hunting and encouraging exercise.

Also, spend time playing with your cat each day. During cold winter months when my cat spends most of his time indoors he plays with a laser pointer. Of course, I have to work it, but it never fails to get him running and chasing the red dot!

Most cats that are allowed outside access get plenty of exercise. Chasing prey, climbing trees, and exploring, not only keep your kitty fit, but mentally active as well.

Could boredom be making your cat overweight

It’s not uncommon for people to eat out of boredom and the same applies to our pets. Snacking on chocolate or fat laden deserts is something most of us have done at one time or another!

Unlike dogs, cats usually know when they’ve eaten enough. However, this doesn’t necessarily stop them worrying for food!

It’s easy to spoil your feline friend and pestering for food out of boredom is quite common. This is why it’s important to keep your cat occupied and her little kitty mind off food!

One good tip is to feed your cat using a food puzzle. You don’t need to do this with every meal, but maybe once a day.

Food puzzles get your kitty mentally active as she works out how to pull the food from the container. This simulates hunting prey, and challenges your cat. It’s excellent for relieving boredom and your cat gets a reward as well!

As your cat is only gets a small amount of food at a time it slows down her eating. This mimics how a cat would eat in the wild.

Hunting and catching prey is usually done in small bursts of activity throughout the day. The rest of the time is spent conserving energy!

What to do if your cat is underweight?

If your cat is losing weight but eating, you need to get her examined by a vet. Older cats are prone to kidney disease, and gradual weight loss is a common sign.

Even younger cats can suffer from diseases that lead to weight loss. If you feel you should increase the amount of food you’re giving your cat do it gradually.

As I’ve mentioned before, cats thrive on smaller meals multiple times a day. You could try 3 small meals a day and increase the amounts slightly. Also, provide a bowl of kibbles your kitty can nibble on throughout the day.

Still provide her with wet food at regular mealtimes though, but use the dried food as something to snack on.

If you’ve taken in a stray that had limited access to food, it’s vital you start building her up. Rescue centres do their very best to bring poorly kitties back to health. However, it’s your responsibility to ensure she has a nutritious diet.

Your vet will be able to advise you on the type of food your cat needs to gain weight. Also, he or she may suggest a supplement as well.

Even if the shelter has given your cat a thorough examination and treated her for fleas as well as de-worming. it’s still a good idea to see your vet. This is because you want to eliminate any possible diseases.

Underlying health problems that may cause weight issues

If your cat is gaining weight and you’re not over feeding her, she could have a health problem. Firstly, your vet will carry out an examination including blood tests. After weighing your cat, she or he will feel your cat for any unusual lumps or bumps.

Hyperthyroidism is a condition that can be treated, but causes weight gain. Though not a health problem, pregnancy will cause your cat to gain weight over the coming months.

If you have a female cat that’s not been spayed, this is a distinct possibility! You’ll need to care for your expectant mum and find homes for her babies unless you plan on keeping the litter.

It’s also strongly recommended that you get your cat spayed after she’s given birth. Spaying and neutering prevents unwanted kittens, and is healthier for your cat.

Other health conditions that can cause weight gain include diabetes and intestinal disease. Most health problems can be treated especially if caught in the early stages.

Weight loss can be down to aging. If you have a geriatric kitty that’s over 17 years old you can expect some loss of weight. The same can be seen in very elderly humans.

Kidney disease as mentioned earlier is common in older cats and weight loss is one of the signs to watch for. In addition, some feline cancers cause weight loss.

Tape worms can cause weight loss, and are easily treated. If you get your kitty wormed regularly, you can prevent such infestations.

In conclusion

Hopefully, I’ve helped answer your question “how much should my cat weigh” Remember to always consult your vet if you’re worried or unsure about your cat’s weight.

Most domestic cats keep healthy throughout their lives. Some rarely require veterinary treatment apart from annual inoculations. However, it’s important to monitor your cat for any unusual changes in weight.

Grooming gives you the chance to feel your cat for any unusual lumps as well as bond with her. In addition, you’ll be able to notice if her body shape is changing.

I hope you’ve enjoyed this post and it’s helped you understand a little bit about your cat’s weight. Feel free to share with your friends and family. In addition, you’re welcome to share this pin on your “pets” board.

  1. Kathy,

    I think this article is perfect. Many cat owners really don’t pay too much attention to their cats weight. I had a male cat that was prone to over eating and easily got overweight. I ended up having to put him on a diet because of it. He was white, but he was so big that he actually looked pink because of his size. I was able to get him back down to a normal weight, but I soon learned that the auto feeders are terrible ideas. He literally just ate all day long.
    My Mom over feeds her cats and many are over weight. But they’re on an auto-feeder as well as get fed wet food twice per day, on top of more dry food at night that she considers treats. I’ve tried to tell her that she’s making her cats big, but she doesn’t really listen to me and continues to do what she will.

    I’ll have to get her to read this article!



    • Hi Katrina, glad you enjoyed this post:) Ha ha, yes, auto feeders can be a bad idea! I think my cat would also eat all day long if I let him:) Over feeding isn’t good for your mum’s cat’s health, but unfortunately it can be hard convincing close family members. I’m glad you were able to reduce your own cat’s weight though:)

  2. You have listed some key points around the ideal weight of Cats…and I feel when the Cats get older they are more prone towards weight issues. I really like the suggestion of Food Puzzle to keep the Cats occupied, stimulated and not get bored. Just like humans even Cats can get lethargic and lazy so important to find ways to keep your feline friend active.

    • Thank you Satz:) I’m glad you enjoyed the post and the idea of using food puzzles to help control your cat’s eating. Yes, our feline friends are just as prone to boredom as we are. Lazy cats can be stimulated into action with toys and activities such as scratching posts or cat trees. Thanks for stopping by:)

  3. You have provided all the important information about overweight cats and possible reasons for it very well. Thanks for the great article How much should my cat weight.
    A few years ago, when we had our cat neutered, he gained weight, but then he lost that weight in a few months and is now reasonably heavy again.
    However, we bought our cats a food puzzle toy – it is in the shape of a mouse, and the cat has to make an effort to get briquettes. But that’s just for the game, because we have seven cats, we have briquettes set up all the time.
    Friendly greeting,

    • Thank you Nina:) Yes, neutered males often gain weight. It’s partly due to a decrease in the metabolism. In addition, neutered male cats tend to wander less resulting in less exercise. My cat seems to prefer lounging around indoors instead of chasing around in the garden! Yes, food puzzles are a great way of controlling the amount of food your cat eats. The mouse puzzle sounds great fun for your cats:)

  4. Thanks for sharing this post, Kathy. You’ve done a great job here to show us not only how much should my cat weight, but how to deal with extra and underweight problems too, which is much appreciated.

    One of our cats is, let’s say, mildly overweight. He’s just like that. He likes to eat all the time. However, after reading your post here, I’ll make sure to change his diet and reduce portions as well. Thanks again for sharing this post!

    • Hi Ivan, glad you enjoyed this post, and found it useful:) I know what you mean about cats liking food a bit too much! Mine is the same and worries for food as soon as I step inside the kitchen ha ha! Definitely be mindful of the portions you feed him. Thanks for stopping by again:)

  5. Thanks for sharing all this valuable information about cats’ weight. I personally don’t have a cat, but I think that it’s super cute when I see a fluffy cat. Now I know that even though these fluffy cats may seem cute, they can also be overweight which can lead to health issues.

    Keep up with the good work and keep educating cat owners on how to best take care of their four-legged friends.
