Is your cat obese? 5 ways to help them slim down

National Pet Obesity Awareness Day is October 13. According to a survey conducted by the Association for Pet Obesity Prevention, roughly 60% of cats and 56% of dogs in the United States alone are overweight or obese. While few things are more adorable than an obese cat, obesity in cats comes with a multitude of health risks. Have you been wondering if your cat needs to lose a few pounds? We’re here to share how you can tell if your cat is obese, the potential health problems caused by cat obesity, and five helpful things you can do to help them lose the weight.

What causes obesity in cats?

Just like in humans, the main cause of obesity in most cats comes down to an excess in caloric consumption and a sedentary lifestyle. Many of us have tried fad diets and health food that tastes like cardboard covered in chalk, and most of us have failed to maintain our weight-loss goals for any length of time. In reality, restrictive diets won’t work in the long term because we soon return to our former eating habits. The same holds true for cats. Weight loss requires a lifestyle change, not a diet. If your cat is in a calorie deficit — meaning she burns more calories than she consumes —she’ll be able to lose weight and keep it off. 

However, there are contributing factors to weight gain, ranging from unexpected pregnancy to illness. Weight gain and difficulty losing weight are potential side effects for certain medications. Spayed and neutered cats may gain weight and have a difficult time losing it, too. Certain illnesses, such as hypothyroidism and Cushing’s disease (also called feline hyperadrenocorticism) slow the metabolism and lead to weight gain. If your cat suddenly puts on weight despite her food and activity levels remaining constant, it’s time for a trip to the vet. 

Why obesity is dangerous

While a chubby-cheeked feline is undeniably cute, obesity increases your cat’s risk of developing a chronic disease. Even more unsettling, obesity raises your cat’s risk of mortality 2.8 times. If your cat is obese, she’s at risk of developing one or more of the following conditions:

  • Osteoarthritis
  • Urinary bladder stones
  • Decreased heat tolerance
  • Cancer
  • Skin conditions
  • Weakened immune system
  • Hypertension
  • Heart disease
  • Diabetes mellitus 
  • Hepatic lipidosis

Although larger breeds weigh more, the average cat weighs 7.9–9.9 pounds. If a cat weighs 10%–20% more than average, she’s considered obese. Even without knowing the exact percentage of body fat your cat carries, you’ll be able to see visual changes that indicate weight gain. Overweight cats have soft bellies and a layer of fat over their rib cages. Obese cats begin to look extremely round and may even develop a double chin. We recommend speaking with your vet if you’re concerned that your cat may be gaining weight.

How to help your cat lose weight

If your cat is overweight or obese, she needs to lose weight before she develops a potentially life-threatening condition. Here are five ways you can help your fur baby slim down. 

1. Consult your veterinarian

Before you put your cat on a diet, take her in for a checkup. She may have an underlying condition that’s causing her weight gain, so the vet may want to run tests to determine why your formerly svelte companion has packed on the pounds. Your vet may also recommend a prescription diet to ensure your fur baby’s nutritional needs are being met. 

2. Monitor your cat’s calorie intake

Most of us have counted calories at some point, and it’s equally effective for cats. The average indoor cat needs only 20 calories per pound of body weight. Don’t fill her bowl until it’s overflowing. Instead, feed her the recommended amount and cut back on the treats

3. Spend time playing with your cat

Unlike dogs, who will happily run in circles for hours, cats tend to play in short bursts. Grab a laser pointer or your cat’s favorite toy and sprinkle several play exercises throughout her day. Exercise will not only give her metabolism a boost, helping her lose weight, but active cats also are less likely to suffer from depression and anxiety. 

4. Make her work for her food

If your cat prefers dry food over canned, try making her work for her meal with a food ball. She’ll burn extra calories while rolling the ball across the floor to collect her morsels, providing her with mental stimulation, exercise, and a tasty meal. Food balls also reward your cat for exercising, creating a positive connection between burning calories and having fun. 

5. Keep her distracted

It’s hard to say no to your cat when she’s begging for food, but you’ll have to stick to your guns. Make sure she has plenty of water to drink, which will help her feel full when she’s hungry, and distract her from craving food with cuddles and playtime.

Maintaining weight loss

Yo-yo diets never work for us, and they won’t work for your cat. Speak to your vet about the best way to help your fur baby maintain her weight loss. (You should take your cat to the vet during her weight-loss journey to make sure you’re staying on track.) Continue to control her portions and ensure she gets plenty of exercise, take your vet’s advice, and your cat should be able to keep the weight off in the long term.

Did you find worms in your dog’s poop? Here’s how to identify and treat them
Parasitic worms can cause real problems in pets — here's how to treat them and take care of your furry friend
Dog runs through the grass outside

Keeping our dogs regular is a fundamental part of pet ownership and is usually pretty easy. Their food includes all the nutrients they need plus maybe a built-in probiotic to help maintain digestion. Sometimes, though, you'll suddenly find your pup has diarrhea, and you'll have to figure out exactly what's going on inside. While there are a number of different possible causes, it could be worms, which can turn serious and even into a life-threatening situation if left untreated.
What are parasitic worms?
When we're talking about worms here we don't mean the kind in your yard and we also aren't including heartworm and ringworm. The type that usually leads to vomiting and diarrhea are intestinal parasites, meaning they're living in your pup's gut. There are a bunch of different worms in dogs out there but the most common in dogs are hookworm, whipworm, tapeworm, and roundworm. Each can have slightly varied effects but likely all include problems with your pet's poop.
How do I know if my dog has worms?
Remember vomiting and diarrhea are symptoms of a lot of issues in dogs, everything from eating something they shouldn't have to serious illnesses, like cancer. The best thing to do is call your vet. They will likely have you bring in a stool sample to test for parasites and possibly other conditions -- sometimes our animals catch a tummy bacteria from other dogs that's easy to treat with antibiotics.
Where do they catch worms?
Sadly, some puppies are born with them and that's when they're most fatal, too (particularly hookworms in dogs). In adulthood, your animal might get them from dirt, poop, a rodent, fleas, or another infected pet. It's best to test your pet before bringing them home or make sure the adoption agency or breeder has thoroughly ruled out worms in dog poop. Even then, you might include a fecal examination as part of a routine screening during their first checkup.
How do I go about identifying dog worms?
Some worms are easy to spot with the human eye, and if you notice something in Fido's poop, you should keep it for later and bring it to the vet. Otherwise, you won't always necessarily see the worms, but you'll notice the effects clearly. When you bring in a stool sample, the tests will determine the type of worm, which also can influence treatment.
How do I treat dog worms?
The best way to take care of worms is with preventatives. Check your heartworm or flea medicine to see if they already contain the right chemicals to keep them at bay. That way, the parasites never have a chance to take root inside your beastie at all. However, once the bugs set in, you might need an additional dewormer to get them out. Your vet will prescribe this, possibly over the course of many months.

We say this a lot, but the best defense is a good offense when it comes to worms in dogs. If you're already paying for preventatives, you can look around and see which ones kill the most worms. One note, cats and dogs sometimes do share parasites if they live in the same household. If you find that your pup has caught one of these, you'll need to look at your other pets, too.

Does your cat say ‘meow,’ ‘miau,’ or ‘mjau?’ Here’s how we translate cat and dog language into human around the world
Wondering what your dog or cat would say if you spoke a different tongue? Here's how we interpret our pets

Your pet might only speak one language, but they can learn any human tongue. They probably know their name at a bare minimum and some dogs can learn up to 1,000 words (even cats can learn a few basic commands, whether they choose to do so is a different story).
But how do we decide what they're saying to us? Countries around the world have different ways of writing barks and meows based on how they hear the sounds. We take a look at the art of translating pet language into human.

What do you call 'bark' and 'meow' in other languages?
If you were in Italy, your dog would say "bau, bau," in France, it's "oaf oaf," and in Portugal, they go "au au." Despite all being in one small area of the globe, each of these languages hears our pets differently. In fact, Word Tips, which researched the subject extensively, figured out what terms people use in the 147 most-spoken languages in the world. It found that there are at least 40 different ways that we write out a dog’s bark. On the flip side, while the exact combination of vowels varies a lot, most cats speak words that begin with the sound in the letter "M."
How do we interpret our pets?
When you actually look at the map that Word Tips put together, you might find some pretty big differences. That's because nearly all these expressions are onomatopoeias, meaning we're trying to put letters to the sounds we're actually hearing. When you add in that languages have different rules, you get vastly different spellings and verbalized words to describe our animals, according to Anthea Fraser Gupta, who has researched the topic. But we're all hearing (at least close to) the same sound, so you'll spot a few similarities, too.

Dog scratches their side while in the grass

We could have gone our whole lives without seeing a flea up close under a microscope — they're terrifying! Most of the time, when you spot a flea, it's outside in the grass, or unfortunately, on your dog or cat. It's not pleasant, but at least at such a small size, it's tricky to make out any kind of identifying details (imagine if one of these creatures was actually large enough to look at without magnification assistance).
While it might spook you to take a look at a flea up close, you should be even more concerned about spotting them in the wild, where they might be snacking on your pet and infesting your home.

What do fleas look like?
If you gaze upon the close version of this insect, you'll spot the telltale six legs, brown or reddish body, and tiny needle-like appendages for sucking blood (fortunately no wings). Instead of flying, these little buggers jump from person to pet to grass. They feast on blood from mammals, so they're coming for you and all your furry friends. To the naked eye, you'll likely spot a tiny blackish speck that could be deep in your dog's fur or even crawling on your floor.
What do fleas do to pets?
Mostly, eat them. As with other biting bugs, they inject a bit of anticoagulant in order to keep the blood flowing --  that's part of where the itchiness comes in. You'll notice red spots and lots of scratching if they wind up on your dog or cat. These pests can also cause other more serious problems, such as tapeworm and anemia, so you want to take care of this quickly once you discover the infestation.
What treatment is available for fleas?
Luckily, a little maintenance usually prevents these parasites from moving in. You have a few options to use as a preventative, including oral, topical, or removable. Many choose to give their pets a chewable or a pill (and some combo pills are available that tackle multiple freeloaders at once, like heartworm and fleas).
