How to Help Your Cat Lose Weight

Cats can have issues with obesity just like people. And they will suffer a lot of the same health issues that people have when they carry too much weight on their body.

Diabetes, liver disease, arthritis, urinary problems, lameness, pancreatitis and GI diseases of all types, and skin problems such as dandruff are some these conditions. You want to find the best weight control cat food for your furbaby.

We do the best we can to give our cats the best lives we can and that means helping them maintain a healthy weight. Some cats will stop eating when they are full, but others can be compulsive overeaters. Leaving food out for your cat all the time is not always a good idea.

Your cat may love their treats, but treats are not always "love." And if your cat is overweight and you are spoiling him with food, you are not doing him any favors. Just remember it is up to you to keep your best friend healthy and with you as long as possible. 

5 Tips for How to Get a Cat to Lose Weight

Punze Fat Cat

You may be asking "how do I get my indoor cat to lose weight?" Think about what a person would do to lose weight. Of course, the emotional things aren't going to help your cat, but you can follow these tips:

1. Invest in the best cat food for overweight indoor cats. Weight control food is made specifically for the less active feline. Cat foods with a real protein as the first ingredient are also high quality and they are a good place to start when your kitty needs a weight loss plan. 

2. Control your cat's daily food amount. Most weight control cat foods actually have portion recommendations on the package. We had a cat that lost five pounds (he weighed 20 pounds) over the period of a few years.

He was fed a half to three-fourths cup of food one time each day. You can also break the portion size in half and feed it to you cat twice daily. One of the biggest reasons for obese cats is owners not realizing just how much food they are feeding their cats on a daily basis.

3. Get your cat to move. Movement (exercise) will help your cat lose weight and if you can make it fun for him, he won't mind it and may even enjoy it. Cat's love to chase things that move.

An automatic laser toy is great way to give your cat daily exercise and takes no effort on your part. There are also many toys that are designed for you to play with your cat. I have one cat that will play fetch with an aluminum foil ball until he has no energy left.

4. Another way to combine exercise and meal time is with a puzzle toy. Puzzle toys are devices that hold yur cat's food, but your cat has to work for the food. He has to figure out how to gain access to it. Not only will he eat not be able to eat as fast, you will have to be active to actually get the food.

Wet or Dry Food for Weight Loss?

According to VCA Hospitals,  the best way to lose weight is with a canned diet food fed several times per day, rather than leaving food down all of the time. One of the reasons canned diet foods work better is because finicky felines often prefer wet food to dry.

Our cat lost 5 pounds over a 2 year period and he did it with dry food. It was an indoor cat weight control food and he loved the food. It is not as much about the whether the food is wet or dry. In most cases, it is about how much food your cat eats each day. 

How Long Does it Take a Cat to Lose Weight?

Just like a person, this can vary from cat to cat. With lifestyle changes for your best friend, you should be to see some reduction of weight within a month. An ideal target for weight loss in a cat is 1% - 2% of their body weight per week.

Most cats will be at their ideal weight in 6 to 8 months. There is no set time for a cat to lose weight. The goal is to get the excess pounds off so your best friend can live his best life.

How to Get a Cat to Lose Weight with Multiple Cats

Fat Cat Obesity

The ideal solution is to feed the cats separately. Allow the overweight cat to eat for 15 or 20 minutes and then pick up all food bowls until the next meal time. There are also feeding stations that open by reading your cats microchip (who would have thought).

When my cats needed to lose a few pounds, I reduced the portions of all 3. They all ate together and were usually finished in 30 - 60 minutes. While the 20 pound boy ate more than the 8 pound girl, she was satisfied and he lost weight. I suspect this solution will not work for all cat parents, but it did serve our cats well and produced the desired results. 

Final Thoughts

We at Cat Attitudes take the health of cats very seriously. Having an overweight cat can shorten the number of years that you will have them in your life. Yes, the "fat cat" names may be funny and the chonk chart cracks us up, but having an overweight cat is no laughing matter.

Our cat suffered from asthma, he could not clean himself effectively and it was difficult for him to jump. But with a weight control food, portion control and some added activity, he was able to lose the weight. And to our amazement, all of the obesity related issues disappeared. 

Our guy became a happy and healthy boy again. The vet still considered him "obese", but his breed is known for being large. The change in his body and behavior was incredible. If you have a "fat cat", take the necessary steps to give him back his or her health.
