Weight Management Cat Food: 10 Vet-Recommended Options - a collaboration with Great Pet Care - The Meowing VetWe hear a lot about the obesity epidemic these days. But humans aren’t the only species at risk. Cat obesity cases are also on the rise. According to the latest Association for Pet Obesity Prevention (APOP) report, 61 percent of cats in the United States are overweight or obese [1], up from 57 percent a decade ago. [2] What’s more, overweight pets have become so prevalent, it can be difficult to tell whether your cat is at a healthy weight, or if they could benefit from a switch to weight management cat food.

Scheduling regular veterinary exams for your cat can help you track your pet’s weight fluctuations. But if your cat faces certain risk factors for obesity, a proactive approach to weight management could help you avoid larger health implications in the future.

Some cat breeds, such as American and British shorthairs, may have an increased likelihood of obesity compared to other breeds. Your cat’s sex may also be a factor, as male cats are more likely to gain weight than females. While the benefits of spaying or neutering your cat far outweigh any potential negatives, the procedure can alter feline metabolism rates, which may lead to weight gain. And though experts agree that keeping your cat indoors is safer, indoor cats do face a greater risk of weight gain than outdoor cats.

Even if your cat does not have any of these risk factors, the potential health issues associated with obesity in cats can be daunting. Feline obesity can increase the risk of osteoarthritisfeline lower urinary tract disease (FLUTD), diabetes mellitus, and various cancers. Obesity can also complicate the management of chronic kidney disease (CKD), liver disease, heart disease, as well as asthma, and other respiratory disorders.

Research shows that cat obesity can reduce lifespan by nearly two years. [3] So, if your cat is overweight, switching to a weight management cat food diet could help increase both the quality and longevity of your cat’s life.

What Is Weight Management Cat Food?

While portion control and increased exercise are proven tactics in the battle of the bulge (both for felines and their human counterparts), some cats may require a different approach, especially if they have more than a few pounds to lose. So if the scale isn’t budging (or is moving in the wrong direction) for your cat, it’s a good idea to chat with your veterinarian about switching your pet to a special weight management diet.

Weight management cat food comes in both prescription and non-prescription (over-the-counter) options that are specially formulated to help cats lose weight. Both types typically contain fewer calories than standard cat food formulas, with macronutrient ratios that are lower in fat while maintaining high levels of protein.

These diets usually work by optimizing fat metabolism and helping to induce a state of ketosis, which is when the body burns fat instead of glucose (sugar from carbohydrates) for energy. Weight management cat diets also tend to contain more water and/or fiber than other cat food. This increased volume or bulk helps cats feel full so they don’t eat as much.

Prescription Weight Management Cat Food vs Non-Prescription

Non-prescription weight management formulas can benefit cats with smaller weight loss goals, but primarily function as a maintenance diet to help cats stay at a healthy weight. In contrast, prescription options (also known as veterinary therapeutic diets) work both as a treatment to help facilitate substantial weight loss, as well as a diet to help maintain a healthy weight once those pounds are shed. Prescription formulas also contain added ingredients to help improve metabolism.

Although they may whittle as many pounds off your cat’s waist, non-prescription options are also easier on your wallet. Prescription diets tend to promote more dramatic weight loss, but they typically come with a bigger price tag.

Why Your Vet Might Recommend a Weight Management Cat Food

Weight Management Cat Food: 10 Vet-Recommended Options - a collaboration with Great Pet Care - The Meowing VetSome pet parents may be tempted to take a DIY approach to helping their cat lose weight. But it’s best to involve your veterinarian in your plan, no matter how simple it may seem.

While reducing the amount of regular cat food you serve up at mealtime could help your “fluffy” feline slim down, veterinarians caution against substantial portion reduction, especially in very obese cats. That’s because drastically reducing portion sizes not only cuts calories, it can also inadvertently cause malnutrition by limiting vital nutrients that your cat needs to thrive.

Additionally, if you suddenly switch a morbidly obese cat to a calorie-restricted diet, they can face an increased risk of developing a fatal liver disease called hepatic lipidosis.

Your veterinarian can help you make changes to your cat’s existing diet and lifestyle to promote healthy, gradual weight loss. But, if smaller portions, fewer treats, and more exercise don’t move the scale, or if your cat has a substantial amount of weight to lose, your veterinarian will likely advise a weight management cat food.

In addition to promoting healthy weight loss, specialty weight management cat food can also make the process of losing weight easier…for both you and your cat. Because the formulas contain fewer calories, you can still feed your cat a “normal” portion size, so they don’t feel deprived. And, thanks to extra fiber, weight loss cat food tends to expand in the tummy, giving cats a sense of fullness. The formulas are also designed to be quite tasty and palatable.

As a result, cats often feel more satisfied and less “hangry” when they eat weight management formulas. That can also help reduce the risk of unwanted side effects that often accompany restriction diets, such as begging for food or destructive behavior.

Switching to a Weight Management Food for Cats

Ready to make a switch to ensure your fluffy feline gets or stays fit? Here are some additional factors to consider when switching to a weight management diet for cats:

  • Transition gradually. To help minimize GI upset, such as vomiting or diarrhea, don’t switch your cat’s diet abruptly. Allow their gut to get used to the new food by gradually mixing in increasing amounts of the new diet during a 7- to 10-day transition period.
  • Speaking of GI changes, be prepared for increased flatulence (gas). Due to the high amounts of natural soluble and insoluble fiber in most weight management foods, your cat may be extra stinky for a while. Some cats may also have a change in their stool consistency. Fortunately, GI changes tend to stabilize after a few weeks on the new diet. If you have any concerns, discuss them with your vet.
  • Don’t cut calories too quickly. As discussed, nothing too fast or drastic! To ensure your cat’s weight loss is safe and healthy, don’t eyeball their portions. Be sure to use an accurate, consistent measuring device (either cup or scale) as instructed by your vet to dispense your cat’s food.
  • Limit treats. Calories from treats add up and can completely skew your cat’s weight loss results. Either cut out treats completely or reduce them significantly, and be sure to include their caloric content in your daily plan. If you do choose to treat your kitty now and then, look for low-cal options offered by many weight management cat food manufacturers.
  • Get physical! Pair food changes with exercise and playtime for the biggest positive impact.
  • Explore the best feeding options for your feline. Some cats may fare better with free choice feeding or multiple mini meals (while maintaining the same daily caloric intake) versus one or two large meals per day.
  • Pro Tip: The same psychological tricks that can help humans in their weight loss efforts may work for your cat. Many cats prefer their food in a smaller bowl instead of a large bowl because the smaller bowl looks fuller when filled with the same amount of food. This tactic can help improve your cat’s mental satisfaction at meal times.

Questions to Ask Your Vet About Weight Management Cat Foods

Structure, accuracy, consistency, and regular tracking are important for any weight loss plan. Before and during your cat’s weight loss journey, here are some question prompts that pet parents can ask their veterinarian. The answers may vary based on your cat’s specific weight loss needs, health status, and lifestyle.

  • What is my cat’s current weight, and what does a healthy weight look like for him? The ideal cat should have a body condition score (BCS) of 5/9. This means a cat’s frame should be well-proportioned, a tucked waist can be observed behind the ribs, his ribs can be felt with only a slight fat covering, and he should have only a minimal abdominal fat pad.
  • What diet plan is best for my cat? Every cat is different, so be sure to ask your vet for guidance on what brand of weight loss or weight management cat food would be best for your kitty. They can advise whether your cat needs a prescription or non-prescription diet and how much they should eat to lose weight. Remember, the number of cups or cans of food may vary, depending on the brand you choose and how many calories your cat needs per day.
  • What are the anticipated costs of my cat’s new diet?
  • What if other cats in the house eat diet cat food? A few bites are unlikely to cause harm to other cats in the household, but avoid consistent or sole use in kittens, pregnant and nursing cats, as well as those with certain health issues (such as cancer, kidney diseasehyperthyroidism, and liver disease).
  • How quickly should my cat lose weight? Cats should lose 0.5-1.5% of his or her body weight weekly until the goal is met. Your vet may wish to weigh and reassess your pet every 2-4 weeks to ensure the current plan works as intended.
  • Once my cat has met their goal weight, how can I help them maintain it?  through diet and activity? Is this a temporary or long-term consideration?

Best of luck on your cat’s weight loss journey. As a pet parent, you’re now empowered to speak with your vet about how to aid your kitty in safely achieving their weight loss goals. With some time and effort, you could help add life to her years and years to her life!
