51 Amazing Cat Weight Loss Transformations


Mega-chonky, thicc, and floofy pets might look cuddly and cute but their extra weight isn’t good for their health. Some pet owners have put their chubby cats through ameowzing transformeowtions and turned them into very happy felines.

We have collected some of the very best pics of cats before and after their weight loss journeys to inspire you and your own pets to do the same. Scroll down, upvote your fave happy cattos, and share photos of your own pets in the comments below, dear Pandas. When you’re done petting these adorable felines through your screens, check out our earlier posts about other cats who lost a bunch of weight: Wilford, Bazooka, and Bronson.

“Obesity is our cats' number one health threat. Feline obesity is more than ‘chonky,’ it's a biological time bomb. Obesity in cats is a serious disease with many severe consequences such as diabetes, high blood pressure, kidney disease, and many forms of cancer. The worst part of feline obesity is that it reduces their life expectancy and dramatically reduces their quality of life. Cats with obesity desperately need our help.” Scroll down for the rest of our in-depth interview with Dr. Ward.

Dr. Ward told Bored Panda that around 90 percent of a cat’s weight loss is related to diet and only 10 percent has to do with physical activity. So it’s vital that you don’t overfeed your cat.

“That's what it's so important cat owners precisely feed the correct number of calories each day. I recommend having your veterinarian assess your cat's current Body Condition Score (BCS), setting target an ideal weight, and calculating the number of calories you should feed each meal,” the pet healthcare professional said.

“I strongly encourage cat owners to weigh the food using a kitchen scale. We've done experiments with cat owners and veterinary professionals and have consistently observed that using a measuring cup isn't as accurate as needed to achieve weight loss in many cases,” Dr. Ward said.

“Even feeding as few as ten extra kibbles each day can add up to a pound of weight gain in a year for a cat. Once you get the hang of it, weighing the food takes no more time than using a measuring cup. Finally, work with your vet to adjust the diet or calories every three months if your cat isn't losing weight.”

He continued: “I've seen too many cats who were being fed the same food for months without losing weight. When I ask them why, the pet parent shrugs, ‘I'm feeding the special food my vet prescribed.’ Weight loss is a journey with many unexpected turns and hills; you must stay alert and be willing to take a different path if you're not reaching your objective.”

Dr. Ward said that exercise for cats can be very simple. For example, all it takes are three 5-minute play sessions with a laser pointer, feather duster, or new cardboard box each day.

“I also like using ‘hunter feeders’ and food puzzles to engage a cat's ‘inner predator.’ Use vertical surfaces, climbing towers, and other perches to allow your cat to climb and ‘stalk’ as much as possible. Environmental enrichment and exercise are essential for emotional and behavioral health as well as maintaining a lean body mass.”

According to Dr. Ward, cats can safely lose 1 to 3 percent of their body mass each month, as long as they’re on a vet-supervised weight loss program. “That translates to my target weight loss of about a half-pound per month for most cats. If a cat loses too much weight too quickly or is fed too little, it can develop a life-threatening form of liver failure, so be sure to work closely with your veterinarian before beginning any diet program with your cat.”

Basically my granny was this cat's owner until she died in 2018 (Mitzi was very overweight when my granny adopted her as it was believed she was a stray had been fed by students) and since then Mitzi had unfortunately been stuck going in and out of the shelter for a while and making quite a few headlines and never quite meeting the right owner. Due to a lucky coincidence, a family member of mine who had originally wanted to adopt her in the first place moved into accommodation where pets were allowed at a time Mitzi was back at the shelter and they adopted her finally this year. She's been slowly losing weight and as you can see she's a lot better now! She will never look as slim as she weighs unfortunately due to her excess skin but she's in a much healthier place than before and her temperament has improved dramatically!

Currently, nearly 60 percent of all indoor cats in the United States are overweight. Carrying around a lot of excess weight has negative effects on your cat’s quality of life; they’re much happier and healthier when they’re sleek and slim. Obesity increases your cat’s risk of getting diabetes. The good news is that shedding the pounds can, in some cases, get rid of their diabetes completely.

Obese cats are also at risk of contracting feline lower urinary tract disease (aka FLUTD): losing weight, changing your cat’s diet, and helping it manage stress all help get rid of it. Meanwhile, fat cats are nearly 5 times more likely than lean felines to develop lameness.

All that extra weight can lead to a lot of other health issues. For example, fat tissue can be a source of constant inflammation throughout the body and this can lead to other diseases. All that fat tissue is also sending out stress-increasing hormones throughout your cat’s system. So even if your chonky catto seems fine, it’s best for it to drop a few pounds before real problems start showing up.

The best, overarching reason for keeping your cat slim is longevity. Pets that aren’t obese lead longer, healthier lives. So you’ll have the pleasure of being ignored by your cat far longer if you don’t overfeed it. And remember—it’s not just about losing weight, it’s about keeping it off.

Speaking of overfeeding, clinical nutrition professor Megan Shepherd from the Virginia-Maryland College of Veterinary Medicine told NPR that there are plenty of owners that struggle with not giving their pets too much food.

“It's not hard to overfeed them in a 'food is love' culture,” Shepherd said.

When I got him he was so shy that he only came out at night. He's lost about 1.5 kg (about 3.3 pounds) since January. Went from 6.9 kg to ~5.4-5.5 kg.

Bosie (full name: Lord Alfred Pawglas, customarily addressed as "His Lordship") is a 7-year-old tabby striped calico boy who was surrendered because he couldn't cope with the addition of two babies, two other cats and a dog to the household (all in <2 years!).

Dechonking him mostly took switching him to moderated amounts of wet food with a very small portion of kibble per day in a puzzle feeder or puzzle toy.
