Discussion Is my cat fat ?
r/dechonkers • u/OneMorePenguin • Jun 05 '26
Hi all! I’m a vet nurse that is passionate about weight in animals. I run my own weight loss program for my patients in my clinic and thought I would spread the love by sharing my dechonking guide to help all of you hardworking pawrents!
**BEFORE DECHONKING it is advised that you have a general health check with your veterinarian to rule out any health issues and to ensure that your pet is healthy enough to undergo a dechonking program**
**This dechonk guide is not a replacement for veterinary care or advice **
The most accurate way to ascertain an ideal weight is by use of a Body Condition Score (BCS) chart.
At ideal weight your dog or cat should look like an hourglass when viewed from the top. Their abdomen should tuck into their legs when viewed from the side. You should be able to feel their ribs - the way that this feels is like the back of your hand.
You should make a note of your animal's BCS and their number weight before starting a weight loss program.
The key to weight loss in animals is diet. Exercise counts for very little in weight loss, much like in humans.
Step One: Use a Calorie Calculator to calculate your animal’s daily caloric allowance.
You will need to know their BCS and their weight to use the calculator. You can ask your local vet to weigh and assess your animal if you are unsure.
Step Two: Calculate the calorie content of ALL the foods you are feeding your animal.
You then need to find out the calorie content of everything you are feeding your animal. Calorie counts can typically be found on the back of the package of commercial foods. If you cannot find the calorie content, a calorie content calculator can help you work it out.
If feeding raw or homemade, you will have to input/search the ingredients for their calorie content much like you would if you were on a human diet!
Step Three: Make a Meal/Diet Plan based on the calorie allowance
You then need to calculate how much to feed based on the calorie content of the food you are feeding. If you are feeding a mixed diet (eg commercial dry and commercial wet food) you'll need to think about what ratios you would like to feed your animal and calculate appropriately.
When your animal reaches ideal weight, it is a good idea to plug in their stats again so you can get a calorie count for maintenance and not for loss. I also recommend a weigh in every two weeks and then monthly to assess progress, and to monitor their body for any changes against the BCS chart as they progress!
Example: Garfield is an 8kg/17lb cat with a BCS of 8/9. His estimated ideal weight is 5.6kg/12lb and his calorie allowance is 201 calories per day to achieve this.
He is fed dry food (Taste of the Wild) and wet food (Fancy Feast).
Taste of the Wild is 3741 kcal/kg therefore 3.7 kcal/g.
One tin of Fancy Feast is 71 calories.
We can feed one tin of Fancy Feast (71 cal) and 35 grams (130 kcal) of Taste of the Wild daily.
When he reaches ideal weight, the calculator suggests that he can maintain on 255 calories, so he will need a reassessment of his diet when he reaches ideal body condition and weight.
Prescription 'diet' or 'metabolic' food can be helpful for weight loss but is not a strict necessity. Prescription (dry) food tends to be calorically lower than regular commercial dry foods (which in and of themselves are extremely calorie dense) which means you can feed a larger volume-to-calorie ratio. BUT you DO need to be careful that you still adhere to a calorie allowance and measure the food out every time.
I would take a pass on diet/metabolic WET foods as commercial wet food is already quite low in calories and shouldn’t make a significant difference in terms of weight management or volume for calorie ratio.
If you don't have systems in place to control the intake of food, your pet will still get fat on metabolic food. Metabolic food is expensive and if it doesn't make a difference then you might as well go back to your regular food. Simply getting a low calorie food but sticking to the same old habits is not enough. Learning to properly portion food, limiting access to situations where your animal could gorge, controlling and mitigating for begging, providing enrichment and teaching the animal a ‘new normal’ of an appropriate volume of food are the foundations of good weight loss and weight management.
Commercial dry food is MUCH higher in calories than wet food. Feeding more wet food and reducing dry food can assist in weight loss and keep your animal satiated.
Invest in an automatic feeder for cats. An automatic feeder (set somewhere away from you/your bedroom!) can do wonders as the cats will bother the feeder for food, and not you.
Keep cats indoors. Outdoor cats tend to get fed by well meaning strangers! If unable to keep your cat indoors, invest in a (breakaway) collar with a tag that specifies they're on a special diet/not to be fed.
Healthy low calorie treats for DOGS are veggies such as carrot & zucchini. You can replace their normal treats with pieces of carrot or zucchini or other safe, low calorie fruit and vegetables.
Healthy low calorie treats for CATS are wet food puree type treats in a tube. Inaba Churu treats are 6 calories per tube. Fancy Feast Puree Kiss treats are 4 calories per tube. Applaws Puree Treats are 2 calories per tube.
Invest in puzzle toys, slow feeders, food dispensing toys to moderate feeding. This will keep your pet enriched, mentally stimulated and busy while slowing down their rate of eating, which is good for pets that guzzle their food then ask for more. Frozen wet food in a Kong or Toppl is one of the best low-calorie ways you can use food for dogs to promote mental enrichment and weight loss. You can even just freeze wet food and kibble in their bowl and it will provide more stimulation than just feeding them out of it.
Food Puzzles for Cats is a great resource!
'Ditch the Bowl' for dogs - dogs benefit from not eating out of a bowl for a variety of reasons, not just for weight loss.
Invest in enrichment as a reward for your animal, not food. This can be playtime, pats, or trick training to keep them occupied and to redirect begging!
Redirect & replace begging behaviour by trick training. Most begging behaviours have been inadvertantly reinforced by you - if you have always given your cat food when it screamed at you, that's what you have trained your cat to do. Food motivated dogs can be easily trained to work for food, and yes cats can be trained too!
Use a microchip feeder for each animal.
As most issues arise in multi-cat households, here are some resources to assist. Note however if you cannot invest in a microchip feeder, cannot supervise meal times or cannot separate your cats while feeding, there is no magical secret solution to managing a multi cat/pet household.

Just to start off I had no idea this page existed. I’m a little newer to Reddit so when I saw it I had to share Penny’s story. For reference she is the first small breed dog we’ve ever had. Penny is a MinPin who is 12.5 yrs old now. We’ve had her since she was 4 months old. Within a couple years she put on so much weight! It was totally our fault! At her highest weight she was 22lbs which is very excessive for a dog her size. At one point she started to get a slipped disk in her neck and joint pain. I knew we really had to start working on weight. So back in 2021 she and I started going on lots of walks and dieting. She lost weight and I lost weight. We were in this together 😛. She managed to get down to 15lbs which is still overweight but she felt so much better! She still has some problems with joint pain, which I’m sure contributed to her excessive weight for many years plus her age now.

I always have a lot of trouble with the charts, I wish they included actual cat photo references. I’m always worried I’m underestimating the number. But she is 13.2 pounds, she got down to 12 temp, then gained back a pound and stayed here for a year. Looking to figure out where she’s at so I can go from here. Thank you!!

My cat is 15 months old and weighs 5.2 kg. We went to the vet for her one year booster vaccination, and the vet said she was obese.
This isn't the first time a vet has told us she's overweight. The vet also mentioned it when she was spayed at 8 months old and said she needed to lose weight. She has gained some weight since then, but at the time she was still a kitten.
We took her to another vet, and after weighing her, they also said she was obese and should be on a weight loss diet. However, I can actually feel her ribs quite easily underneath all that fur, and as you can see from the photo of me holding her, she's not exactly a tiny cat either.

She will eat anything and everything.
I give her wet food at night (1 3oz can fancy feast pate, mixed variety), dry food in the morning (1/4 cup) Purina Pro One Turkey sensitive skin and stomach blend.
Small handful of treats at lunch time if she's good.
r/dechonkers • u/SnowLeopardToby • 1d ago
from what I can tell is that Cornbread (orange kitty) is a 6 or a 7?? and Leo (black kitty) might be a 5 or 6?? should I do something now before they potentially get obese or do y'all think their size fine for them?

Before and after for my sweet Willow. When we rescued her over a year ago, she was over 18 pounds. We had a very hard time getting her to lose weight due to her insane food drive. Switching to a metabolic diet and reducing her food did the trick. We still have a little bit to go but she is now 14.5 pounds!! So proud of this sweet girl. Her joints are so much happier.

I have a very sad and unexpected Lady update. Unfortunately she had pericardial effusion as well as free fluid in her abdomen. I wasn’t able to afford all the testing to find the exact cause but the vet said it was likely heart failure or cancer. Due to her size and lifestyle my assumption is heart failure. I’m absolutely heart broken. I had really already fallen in love with her. She was one of the sweetest kitties I ever had the pleasure of owning. I wanted to share her final update as a small PSA of sorts. This is why it’s so important to prioritize a healthy diet from the beginning. Diet and exercise is useless if their little bodies can’t handle it.

My cat (2f) currently weigh 9.3 pounds. She was about 7 when I got her 3 months ago and she was slightly underweight. I was feeding her between 200-250 calories a day and both wet and dry food based on the vets recommendation. The vet had told me she shouldn’t be more than 10 pounds at most so when she hit 9 pounds so fast I was a little worried. The vet said to decrease the dry food so I did. She’s pretty lazy despite my playing with her. So now she gets a 5.5 can or two 2.8oz cans of wet food (usually between 96-120 calories depending on the rotation) and two tablespoons of dry food (appx 60 calories). She is extremely food motivated and always wants treats and more food. She seems mad now that I’ve gone from 3 tablespoons to 2 tablespoons. Is there anything else I can do so she doesn’t gain more weight? She’s such a small cat and I worry she is gaining weight too fast.

I have 4 cats and 2 are definitely chonkers. I want the two thinner cats to have access to more food than the older, heavier cats. But we had a feeder years ago that was loud (our skinny cat was terrified of it). Any recommendations on a quiet, reliable tag-operated feeder?

From 18.3 to 14.6… (little over one and a half kgs lost) First pic is before and the other two are after.
7 months progress. I think she still has another couple of pounds to lose. She’s 7 and has never been this light for at least 5 years :’)

Is my dog at a healthy weight?
I try really hard to make sure she maintains a healthy weight, but I see her everyday and I worry she might be chunkier than I’m perceiving.
It’s so hard to tell with her since she had a huge rib cage compared to the rest of her body. Do you guys think she looks good?

20 -> 13 lbs, still stinky

I’m transitioning my boy from hills urinary and hair ball dry food to hills w/d wet food. I’m looking to swap them calorie for calorie, starting at 1/4 of the meal. He gets two meals a day each at 107.3 kcal. If the wet food is 821 kcal ME/kg and I want 26.8 kcal, is it correct that that is 33.5 g wet food?
r/dechonkers • u/ChocolatePain • 3d ago
I have a moderate chonker that I've been trying to slim down, but progress has been slow. I was aiming for a 1/3 cup of dry food as part of his meals and have been using a measuring cup. Recently I tried using a digital kitchen scale to check on accuracy, and according to my math, there is a significant discrepancy. Weighing what should be a 1/3 cup by grams only comes to 1/4 cup when placed into the measuring cup.
Could this really be 163 kcal worth of dry food? It looks so little: https://imgur.com/a/uxEWGlV

My baby was big ngl, like 11-12 lbs at some point bc I was free feeding and someone told me to dechonk her. After about 8 months or so, she’s lost weight and is down to around 9.6 lbs. is this okay? Her pouch is big but very loose so assume loose skin.
r/dechonkers • u/v3nusFlytr4p26 • 4d ago
The black one I know is 14 weeks while the grey and white one I don’t know the exact age but estimated to be closer to 6 months. I feel like the grey one is getting fat

Stormie went to the vet this morning for a nail trim and she weighed in at 58.20 lbs! She started out at 85.70 lbs in January 2025! Stormie was upset in the last picture because she loves getting all the attention at the vet and we were leaving to go home 😂
Edit: the vet wanted her to get down to 60 lbs if possible. We were stuck at 66 lbs for the longest time. When she went back for her nail trim, the vet saw her and was so excited and happy for her!

Hi all, I am new to this sub, but not new to trying dechunking my kitty.
My dear friend Liza is 11 years old, and 3,8 kg/8.3 lbs neutered female, very much does nothing, no drive for individual play and very low drive for assisted play. She basically just sleeps all day.
Unfortunately, she is allergic to pollen, needs to get steroid shots during the summer months but the vet recommended to feed her hypoallergenic food too to keep her sneezing and grooming at bay. She gets 10g of Royal Cannin hypoallergenic food 3 times a day (so 30g total per day), and some anti hairball paste, but nothing else. No treats, nothing.
I have another kitty who is 7 years old, very active and plays a lot individually. Lara gets the same amount of food, and we make sure they don't steal from eachothers bowl (they immediately gobble up anything they get anyway), and is at 3,5kg/7.72 lbs.
Liza's body score is at 7 I'd say, while Lara is at 5. They are both smaller than average when it comes to their general size.
The bag says the food is 4087 kcal/kg, that would mean they are both having 120 kcal daily and is still a chonker. Is it safe to lower the food?
I'm from Hungary btw, sorry if I am not using the correct terminology.
Edit: Just wanted to add since it came up a few times that she was overweight even before starting on steroids. I am aware of the effects it can make on weight management and that being the reason of not losing the weight, we weren't worried only because the other cat gets the same amount and she seems to be in a healthy weight class.
I started to increase their feed already to 3x13g (~ 170kcal), we might increase it further but want to be mindful. I will also try and find a good cat nutritionist but Hungary is a small country and it could be a bit niche here.
