Your cat’s diet plays a major role in its well-being. If you feed your cat too much or too little, they won’t maintain optimum health. Likewise, a lack of nutrients can lead to a deficient feline while an overabundance can cause obesity and all the problems that come along with being overweight.

Finding the sweet spot for how much to feed a cat can be difficult, especially for new cat keepers. But in this article, you’ll find all the information you need regarding feeding frequency and amount, helping your cat to live its best life, and taking the guesswork out of the equation.

How Often Should You Feed Your Cat?

This seems like a simple question on the surface, but how would you answer if someone asked how often you should feed a human? We all know that it depends greatly on several factors such as age, size, and appetite. Cats are no different. They eat different amounts, depending on similar characteristics such as age, weight, breed, size, and more.

Younger cats need feeding more often than adults. Growing felines require more food per pound of body weight compared to older cats. Rather than stuff all of that feeding into one sitting, it’s best to spread it out across several feedings throughout the day.

As your cat gets older, it will require less food per pound of body weight, which means fewer feedings. Once your cat reaches adulthood, two or three feedings each day will suffice, so long as your cat is getting all the necessary nutrition within those feedings.

Cat Feeding Chart

To determine the size of the feedings, divide the amount your cat eats by the suggested number of daily feedings. It will be different for each kitten/cat depending on how much they eat from the daily suggested range.

Keep in mind that this chart represents only a rough guideline. The amount of food a cat consumes should be based on daily calories. Different cat foods have specific caloric densities per gram of product. Monitoring a cat’s weight gain during its growth and development and its body condition score during adulthood is the best way to find out how much to feed a cat. 

It’s always recommended to consult a veterinarian if you have any questions or concerns about your cat’s diet.

Factors That Influence How Much to Give Your Cat

As mentioned, many factors influence how much food your cat requires. Although younger cats eat more per pound of body weight, they eat less overall. Larger and heavier cats will require more total food. But as a cat gets larger, they can eat more in a single sitting, so feeding frequency decreases, even though the total amount that is eaten continues to rise.

Another factor to consider is your cat’s current activity level. If your cat is sedentary and spends its time lounging in comfortable spots around the house, then it’s not going to require as much food as a feline that’s always running around, playing, or spending a lot of its time exploring the backyard.

You’ll also have to make adjustments for feeding wet or dry food. While either is perfectly acceptable, provided it offers complete nutrition for your cat, they don’t measure out the same. Naturally, wet food weighs more, so you’ll have to feed your cat more of it in terms of weight. As for deciding how much dry food to feed a cat, you’ll feed less of it by weight, but it will appear to have more volume in your cat’s food bowl.

Health Dangers for Obese Cats

Obesity is a major problem for domesticated cats in North America. It’s the most common of all preventable feline diseases. In America, about one-third of all cats are considered to be obese with about half of all cats over the age of 5 being considered overweight.

So, what problems will obesity cause for your cat? To start, it will shorten your cat’s lifespan. Obese cats show an increase in mortality rates 2.8 times higher than cats of a healthy body weight.

If that’s not enough, obesity also makes your cat more susceptible to other diseases that can decrease the quality of their life and shorten their lifespan.

Cats that are obese show an increased risk for diseases like:
  • Urinary bladder stones
  • Osteoarthritis
  • Hypertension
  • Diabetes mellitus
  • Heart disease
  • Cancer
  • Anesthetic complications

It’s not just being obese that’s bad for your cat. Obese cats that stop eating might even have it worse. When an obese cat ceases eating or loses weight too fast, they often develop a condition called hepatic lipidosis; a liver disease that can be life-threatening.

Obese cats have a much harder time fighting off infectious diseases since their bodies are already in poor health, which means that diseases are more likely to be serious or even fatal.

Monitoring Your Cat’s Feedings

When cats are stressed or ill, they’re often very good at hiding it. Some of the most obvious signs you can look for are changes to their feeding habits. These can also be an indication of how your cat is responding to its feeding routine, allowing you to make any necessary changes.

If your kitten is eating in the middle of the night, there’s nothing to worry about. Kittens have tiny stomachs, which is why their food must be split into many smaller meals. It’s hard for them to go 8–12 hours without a meal, so it’s fine for a kitten to look for a nighttime snack. Adult cats should be used to a particular feeding schedule though, and shouldn’t need to feed in the middle of the night. If your adult cat begins to exhibit this behavior, it might indicate that there’s another underlying issue.

If your cat is licking its bowl clean every time you feed it, it could be underfed. However, you’ll need more evidence to be certain. Instead of guessing, learn what a cat’s body should feel like so you can assess your cat’s weight. Feel for proper rib coverage and weigh your cat to ensure it’s at a healthy weight.

Veterinarians have developed what is known as a body condition score. This system evaluates a cat’s body shape from above and the side as well as how easy or difficult it is to feel the ribs. This system helps to place a cat’s body on a scale that ranges from 1–9. Cats with ideal body weight are in the middle of the scale, at number 5. Underweight cats can be between 1–3, with 1 being emaciated or extremely underweight. Obese cats are placed at number 9, and the range of 7–8 is considered overweight. Using the body condition score with the guidance of a veterinarian is the best way to evaluate and determine how to manage your cat’s diet.

Conclusion

There are no hard and fast rules regarding cat feeding frequency and volume. When deciding how much to feed a cat there are many factors are at play, such as the cat’s age, breed, size, weight, activity level, and more. Still, there are some general guidelines that you should follow to ensure your cat is receiving the appropriate amount of nutrition.

If you still have questions or you aren’t sure if you’re feeding your cat too much, too little, or if it’s a healthy weight, then you can consult your veterinarian to help you get the basics down for your cat.

  1. Thanks for the info on cat's weight and eating recommendations. We use measuring cups to make our cats' portions. It would be helpful if the chart also indicated portion sizes in cups instead of grams.

    Also, we have a one year old female who gobbles anything we give her, and a four year old male who is very picky about eating. It's difficult to keep Emma from finishing off all of Vinnie's meals. So she's getting a little belly starting to form.

    Any good ideas to keep Emma from overeating when finishing off Vinnie's meals?

      Hi Joe, thanks for your comments. Different kibbles have different sizes and densities so it is less accurate to make a calculation in cups. You could try using a kitchen scale to measure the volume of their diet and then mark how much they get in a cup. Your problem with a cat eating all of their portions and then the other cat is quite common and the easiest solution is to separate them during feeding times. Alternatively, you could try an automatic feeder with a microchip reader such as the product listed as #8 here: https://www.catster.com/lifestyle/best-automatic-cat-feeders/
      Kind regards and thanks for reading us, we hope this helps. 🙂

  2. PLEASE put your feeding guides and ALL guides offered in OUNCES not grams OR BOTH oz and g
    Otherwise, for me, NOT useful and I will avoid your emails, website, etc.
    I am waiting to hear your response as I adore my cat sisters of 13 years (litter mates).
    They are in great health, active, fun, silly, & smart. Indoor at sunset and outdoor (backyard) most days.
    Keeping them in great health is my objective and I enjoy lifelong learning about best practices for my girls.

      Hi Deb, thank you very much for reading us. Catster readers are from all around the world and grams is a more universal measure. Also, with such small weight differences, it would be harder for you to calculate 0.07055 ounces for a 2-gram difference, therefore putting it in grams makes more sense. Perhaps you could consider purchasing a kitchen scale, you can set it to grams or oz. Alternatively, there are several online calculators that you could use. If you still need some additional help to figure out how much to feed your cat sisters, please do not hesitate to book a consultation with a veterinarian at www.pangovet.com, they would be happy to assist you. Again, thanks for reading us and sharing about your beloved cat sisters, we are always happy to share knowledge about cats and love to hear about loving pet parents going the extra mile to keep their kitties happy and healthy.
