14 Best Cat Foods For Weight Loss 2021
We love our furry companions and oftentimes, we are quick to overindulge them. We feed them too much food they love and treats just for asking. However, this could get to be a problem if they start gaining weight so it's important to understand what's the best cat food for weight loss.
When a cat is overweight, it can lead to several health issues that could shorten their lifespan. Switching their food to diet cat food made for weight loss can help your cat start to shed those pounds without them even realizing it.
What is The Best Cat Food for Losing Weight?
When shopping for the best cat food for weight loss, you will run into several different kinds of labeling. Some will say “weight control” or “weight management,” some will say “indoor formula,” and others will say “high in protein.” Or, you may run into some foods that have a combination of these labels. But what do they mean?
Cat foods for weight loss all have different pros and cons, but what they all boil down to is what the food was designed for.
Weight control food was specifically made to help cats lose or maintain their weight. Indoor formulas are made specifically for indoor cats because they often do not have the same amount of activity or nutrients as outdoor cats. And high protein cat food includes a ton of protein, especially since large amounts of protein have been scientifically linked to weight loss.
At the end of the day, what you should really pay attention to in the food you feed your cat to lose weight is the number of calories in one serving.
Comparing Calories in Weight Control, High Protein, & Indoor Formulas
Weight Control Cat Food
Naturally, weight control formulas have fewer calories per cup than indoor and high protein formulas usually do. This is because the formulas have weight loss specifically in mind. If you are really trying to cut back on the amount of calories your cat consumes, opt for a weight control formula.
Indoor Weight Loss Cat Food
Indoor formulas fall somewhere in between weight control and high protein formulas as far as calorie count goes. However, just because it may have more calories than weight control formulas doesn’t mean it’s bad for weight loss. They often provide several added benefits specific for indoor cats, such as hairball control and easy digestion.
If you choose an indoor formula for all the benefits combined, just be aware of the number of calories in a serving and make sure not to overfeed your cat.
High Protein Weight Loss Cat Food
Finally, high protein formulas tend to have more calories than weight control and indoor formulas. While that’s not always optimal for weight loss, high amounts of protein can be. Protein helps build muscle mass which helps burn more fat. Protein can also help keep your cat full for longer, reducing the amount you need to feed them.
Since high protein formulas are higher in calories than the other two, you need to be very aware of the number of calories you are feeding your cat so you don’t overfeed them. Check the label and opt for high protein blends that are also low in carbs.
Guide to Buying the Best Cat Foods for Weight Loss
How Much Should Domestic Cats Weigh?
As a general rule of thumb, domestic cats should weigh approximately 10 pounds. However, this isn’t a hard and fast rule. Often a range of weights work for domestic cats and your cat could very well be healthy at 15 pounds.
Does That Depend on Breed?
The amount of domestic cats should weigh really depends on their breed. Several breeds of cats are bulkier and naturally heavier than other breeds. For instance, Siamese cats could be healthy at just 5 pounds while Maine Coon cats can be healthy at 25 pounds.
What is an Obese Cat?
Cats are considered obese when they are 20% heavier than their ideal weight. They are considered just overweight if they are 10-19% heavier than their ideal weight. You can also usually tell if a cat is obese by the way they look. If it is hard to palpate a cat’s ribs and spine and it is hard to see their waist due to fat, they are more than likely considered obese.

Health Risks for Overweight Cats
Just like in people, obesity in cats can put them at risk for several health problems. First, the excess weight can take a toll on their bones and joints and make them more prone to developing arthritis faster.
Not to mention, it can wreak havoc on cats’ organs and make them more prone to diabetes, heart disease, and liver disease. In the most extreme cases, it could even cause cancer in cats.
The gist of the matter is obesity could shorten a cat’s lifespan dramatically if not taken care of.
Why Your Cat Could Be Overweight
There are several reasons your cat could be overweight. Just like when humans are overweight, a combination of factors could be involved, especially when it comes to food and exercise.
Indoor cats are often not as active as outdoor cats. If they are not staying active enough, they could start to gain weight, especially if their diet does not reflect their level of inactivity.
Feeding your cat too much or too frequently could also result in their weight gain. Sometimes the food they eat has too many calories, their portion sizes are too large, and they get too many treats. Also, if you just leave dry food down for them all day long, they may become little gluttons and pig out too frequently.
We know it’s hard to resist that cute, furry face when they’re begging for treats or more food, but putting your foot down and monitoring their diet may just be what helps keep them healthy for a long time.
Weight Loss Tips for Cats
There are plenty of simple things you can do to help your cat lose weight. First is getting them to move more. More movement means that they burn more calories. Make sure they have plenty of toys that they are interested in and even take the time to play with them to keep them moving.
You could even be sneaky and move their food or litter box further away so they have to move more to get where they want to be.
Next, control what they eat. Feed them smaller portions and change their diet to a food that helps with weight control. A great way to reduce the amount they eat without them getting angry at you is to use interactive feeding.
