How Much Should a Cat Weigh: The Ideal Bodyweight for Different Cat Breeds

For cat parents, keeping their pets healthy is a big concern. And when it comes to a pet’s health, weight is a good indicator. If you’re asking how much should a cat weigh, wouldn’t it be nice to have someone help you find out the ideal weight for your pet without having to take a trip to the vet?

The weight of cats will depend on their age, sex, size, and breed.

Knowing the ideal weight range for your pet will help prevent unnecessary worries about your pet’s health.

Weight is not the only indicator of whether your cat is healthy or not, so we’ll give you some tips on how to manually check if your pet is becoming fat.

When you’re aware of the signs to watch out for, you can immediately take action to prevent your pet from developing obesity.

If in case your pet is already obese, we’ll give you some tips on how to manage your cat’s diet so you can nurse your pet back to a healthy weight.

3: Ideal Weight Range for Kittens

Not being sure if your kitten is growing well is always a source of worry, especially for first-time cat parents. Kittens normally grow very rapidly, especially during their first three months. They then continue to grow, albeit at a slower pace, until they’re a year old, by which time they’re no longer considered kittens.

If you’re wondering how much should a 1 year old cat weigh, the answer will vary, again depending on the breed and sex. Some will continue to grow until they’re a year and a half old, while breeds like the Maine Coon take about two years to reach maturity.

Here’s what to expect with your kitten’s growth development.

  • Weeks 1-4. Newborn kittens weigh only several ounces, but during their first month, they can show rapid growth. It’s easy for a kitten to grow from just 3 ounces to more than a pound.
  • Weeks 5-8. By week 5, the mother cat will usually start the weaning process already, so this is a good time to start shopping around for kitten food. This is also a great time to start training your kitten to socialize with humans. If you’re keeping track of your kitten’s weight progress, your pet can grow up to around two and a half pounds at this stage.
  • Weeks 9-12. In their third month, kittens can grow from less than 2 pounds to more than 3 pounds. By this time, you can already give them wet and dry kitten food.
  • Weeks 13-16. Kittens who are already in their fourth month can grow from just over 2 pounds to more than 5 pounds. This is the time when kittens test their own physical limits, so you might find their antics a bit trying. Moreover, some of them will start growing their adult teeth already, so watch out for chewing behaviors. Scent marking behaviors also usually begin at this stage.
  • After 16 weeks up to one year. You can think of your kitten as an adolescent now, and he/she will probably show the same adolescent behaviors like human teenagers do, such as being aloof and a bit rebellious. Weight gain will continue, however at a slower rate than during the first four months.

How to Manually Tell If Your Cat is Fat

Cat is Fat

Cats, like humans, can become obese. If, in humans, two extra pounds don’t really matter much, in cats, it can mean the difference between healthy and obese.

For instance, if your cat’s ideal weight is 8 pounds but your pet is weighing 10 pounds, that’s already 25% more than the healthy weight. And it can lead to a lot of health problems for your pet later on, like high blood pressure, diabetes, or heart diseases. Read on to find out more about visual clues that tell you your cat is getting fat.

  • Hourglass Figure. Have your cat stand on all fours and look at your pet from above. You should see a waistline, and the outline of your cat’s body should be like an hourglass. For long-haired cats, this may not be easily visible, so you might need to feel for it manually. If your cat’s waistline is starting to disappear, you should start thinking about having your pet go on a diet.
  • Abdominal Tuck. You will find a cat’s abdominal tuck in between the ribcage and the pelvis. In very thin cats, the abdominal tuck will be very pronounced, whereas, in overweight cats, it will only be slightly visible. If you don’t see an abdominal tuck at all, it could be a sign that your cat may be obese.
  • Ribs. In very thin cats, you won’t even need to feel for the ribs as they will be clearly visible. In cats with healthy weights, you can easily feel the ribs, but you will also find that it is slightly covered with fat or flesh. In overweight cats, however, you almost can’t feel the ribs, and in obese cats, it will be very difficult to feel them, if at all.
  • Fat Deposits. This is a sure sign that your cat is obese. When you look at your cat from the side, you will see fat deposits around the neck as well as on the limbs. If your cat’s belly is sagging too much, it could also be a sign that your cat is already obese.

What to Do If Your Cat Is Obese

Obesity in cats is downright unhealthy. It can lead to arthritis, and joint pains as your pet’s limbs start having difficulties carrying the extra weight around. It can also lead to more serious conditions such as diabetes and heart diseases.

Here are some tips for you to help your cat lose those extra pounds.

  • Switch to Canned Food. If you’ve been feeding your cat dry food, it would be a good idea to switch to canned cat food instead. This normally contains fewer carbohydrates and more proteins than dry food. Moreover, you can easily set your cat’s eating schedule with canned food, whereas if you just leave dry food in your pet’s bowl, your pet can go back to the feeding bowl anytime he/she feels like eating.
  • Minimize Treats. Treats are a great way to reward your pet’s good behavior, but you can easily replace them with a different reward system when your cat’s already gaining too much weight. Instead of treats, you can give your cat a new toy to play with. It will also encourage your cat to move around and give him/her the exercise he/she needs. Using balls as toys is a good idea to force your cat to run around and get some workout.
  • Move the Food Bowl Often. If your fat cat has a habit of sleeping near the food bowl, it’s a great idea to move the bowl to different places. This will not only force your pet to walk around the house and look for his/her food, but it should also break their habits of sleeping near where their food is located. Don’t worry, cats are very smart, so your pet can definitely find their food bowl no matter where you hide it inside the house.
  • Feed Separately. Many cat parents have multiple cats in the house. If this is the case and one of the cats is overweight or obese, it would be a good idea to feed that cat separately. You can take your overweight cat into a different room to feed. If you’re feeding your other pets at the same time, make sure the overweight cat isn’t able to leave the room to join your other pets. Once feeding time is over, make sure that there’s no pet food lying around. Your other cats might need to sacrifice a little for the sake of your overweight cat, but this is a good way to train them on feeding time.
  • Visit the Vet. If your cat is already showing signs of being overweight, take your pet to the vet right away. Having your pet checked as soon as possible will help prevent health problems that might crop up later on. Moreover, your vet can give you good advice on how to keep your cat healthy and how to prevent your cat from becoming obese.
