How Much Should I Feed My Overweight Cat?

If you have an overweight cat, it can be difficult to determine how much to feed your cat. You want to make sure that your cat is met with the right nutritional needs while promoting healthy weight loss. And it can be even harder if your cat is either a finicky eater or seems to be hungry all the time.

Whether you feed dry food, wet food, or a mix of both, understanding the correct portion size and feeding strategies can make a significant difference in your cat’s health and longevity.

Understanding Feline Obesity and Its Risks

Before diving into how much to feed your overweight cat, it’s important to recognize that obesity in cats is not just about appearance as it is a serious health issue. Overweight cats are more likely to develop diabetes, arthritis, heart disease, and even certain cancers. Extra weight also puts stress on a cat’s organs and joints, reducing their quality of life and shortening their lifespan.

If your cat is overweight, your veterinarian can help determine an ideal target weight and guide you through a safe feeding and weight loss plan.

How Much Food Does an Overweight Cat Need Per Day?

A good rule of thumb when trying to reduce your cat’s weight is to feed according to their ideal body weight and not their current weight. In general, a cat needs about 20 calories per pound of ideal body weight per day to maintain that weight. For weight loss, reduce that intake slightly under veterinary supervision or usually closer to 15–17 calories per pound of ideal weight.

For example, if your cat’s ideal weight is 10 pounds, aim for 150–170 calories per day. Always check the calorie content on your cat food labels to measure accurately, as different brands vary widely. If you're unsure, start by calculating the total daily caloric requirement and divide it between the number of meals your cat receives in a day.

Wet Food vs. Dry Food: Which Is Better for Weight Loss?

When feeding an overweight cat, wet food is often preferred over dry kibble. Canned food has a higher water content, which helps your cat feel more satiated (and fill up) with fewer calories. Additionally, wet food tends to be lower in carbohydrates and higher in protein, which better aligns with a cat’s natural dietary needs.

Dry food is more calorie-dense, meaning it's easier to overfeed, especially if your cat is free-feeding. If you prefer or need to use dry food, it’s important to measure it precisely with a kitchen scale or measuring cup and stick to your cat’s daily calorie limit.

For example:

Dry food: A typical cup of dry cat food contains 300–500 calories. An overweight cat needing only 150–170 calories a day should get just about 1/3 to 1/2 cup or less, depending on the brand.

Wet food: A 3-ounce can of wet cat food contains about 70–100 calories. Your cat might need two to three cans per day, split across multiple feedings.

Another important factor in helping your cat lose weight is to make sure he or she gets exercise. And gets moving! Not unlike humans who want to lose weight.

What If My Overweight Cat Is a Finicky Eater?

Feeding an overweight cat is challenging enough, but when your cat is a picky eater, it can be even harder. The key is to introduce changes gradually. If your cat is used to a high-calorie dry food, try mixing a small amount of wet food into their meals and slowly increase the ratio over several days. Some cats are texture-sensitive, so experiment with pâté, shredded, or minced varieties to find what they like.

Don’t free-feed or leave food out all day. Instead, feed at scheduled times and remove any uneaten food after 20–30 minutes. This not only helps control portions but also trains your cat to eat more promptly.

You can also warm up the wet food slightly or add a splash of warm water or low-sodium broth to make it more appealing. Always avoid feeding human foods or high-calorie treats and choose low-calorie cat treats if needed. No treats at all is even better.

How Often Should I Feed My Overweight Cat?

Instead of one large meal, split your cat’s daily food into two or three smaller meals. This can help manage hunger and support better digestion. If your schedule allows it, multiple small feedings throughout the day mimic a cat’s natural hunting behavior and may reduce food-related anxiety.

Automated feeders can help maintain consistency, especially with dry food. Just make sure the feeder dispenses pre-measured portions to prevent overfeeding. For wet food, you can give the required amount twice a day or in smaller portions, three times a day.

Monitor Your Cat’s Progress and Adjust as Needed

Helping your cat lose weight safely takes time. Aim for a slow gradual weight loss. More rapid weight loss can be dangerous, especially for obese cats who are at risk of hepatic lipidosis, a life-threatening liver condition triggered by sudden weight loss or food restriction.

Weigh your cat weekly using a pet scale or a baby scale and keep a log of their progress. If the weight isn’t coming off, revisit the food label, adjust portions, or consult your vet. Exercise also plays a role, try engaging your cat in play with feather wands, laser pointers, or treat puzzles to help burn calories.

If your cat cries for dry food and you have already fed your cat the proper amount, try to ignore your kitty. Don’t give in and if anything, give your cat a little more wet food.

Final Thoughts: A Lifelong Commitment to Healthy Feline Feeding

Knowing how much to feed your overweight cat involves more than just portion control as it’s a long-term commitment to their health. By feeding the appropriate number of calories, choosing the right balance of wet and dry food, and staying patient with picky eaters, you can help your cat return to a healthy weight.

Always involve your veterinarian in any diet change, and remember that consistent feeding routines, portion awareness, and a little creativity with finicky cats can go a long way to help your favorite “chunky” feline lived a longer, healthier life.
