Overweight Cat Statistics

A study by the Association of Pet Obesity Prevention in 2011 revealed that 53% of cats in the United States were either overweight or obese.

This means that more than 50 million cats in the US alone are struggling with weight gain, an increase from a 2007 study that showed only 19% of cats were obese.

Just as obesity causes other health complications in humans, cats are not spared either.

Overweight or obese cats are subjected to other health complications such as diabetes, arthritis, high blood pressure, kidney disease, arthritis, etc.

If your cat is among the statistics, you should take quick action before the condition leads your cat to serious health complications.

The good thing is, you can help your cat lose weight in a healthy way.

What To Do About Your Cat’s Weight

Causes of Excess Weight Gain in Cats

Eating More Calories Than Your Cat Burns

The major cause of obesity in cats is taking in more calories than they burn.

While most cat parents will deny it, most cats are treated to free choice feeding where food is available all the time and the cat eats whenever they want.

After their stomach is filled to the brim, kitty then spends most of the day lazing around waiting for a refill when the sucker (you!) is back.

The effect? Packing on the pounds and increasing gradually in weight every…..single……day.

Sounds like the typical indoor cat! Right?

Little To No Exercise

Indoor cats are more likely to gain excess weight because they have little room to run and climb like their outdoor counterparts.

Usually, indoor cats spend most of the time sleeping, with fewer opportunities to exercise and lose some pounds of fat.

Spayed Or Neutered Cats

Spayed or neutered cats are also at risk of becoming obese.

The effect of neutering or spaying on the physiology and behavior of your cat increases the chances of your cat becoming obese.

The weight gain in spayed or neutered cats is mainly caused by increased food intake.

Ideally, neutered or spayed cats should consume fewer calories than cats that don’t undergo the procedure.


Overweight cats are at risk of developing chronic diseases like arthritis, cancer, cardiac problems and diabetes.

Helping your kitty maintain a healthy weight ensures they lead a full and healthy life.

Giving your cat wet cat food keeps them cat feeling full on fewer calories due to the high moisture content.

Make sure to talk to your veterinarian regularly to monitor your cat’s weight loss journey.

A strict commitment to your cat’s diet is significant in attaining the desired body weight.
