How To Spot Your Maine Coon Is Overweight

Maine Coons are the largest domestic cat breed, with muscular builds, long frames, and thick coats that easily disguise extra fat. Their slow growth (taking 3-5 years to mature) makes it even harder to judge whether a big Maine Coon is overweight.

But carrying too much weight is dangerous; it can shorten their lifespan, stress their joints, and raise the risk of:

• Heart disease
• Diabetes
• Breathing problems

The good news is that with careful observation, you can spot early signs of weight gain and take action before it affects your cat’s health.

Below, I’ll break down in detail how to tell if your Maine Coon is overweight, the most common causes of obesity, and simple but effective tricks to keep your cat at a healthy size.

Signs Your Maine Coon Is Overweight

Maine Coons are naturally big and fluffy so you’ll need more than just a glance to know if they’ve crossed into unhealthy territory.

Here’s how to check properly:

1. Feel The Ribs, Don’t Just Look

A healthy Maine Coon’s ribs should be easy to feel with light pressure, even under thick fur. If you have to press firmly, or if the ribs feel like they’re buried under a layer of padding, your cat has likely gained too much fat.

👉 Tip: Run your fingers gently from behind the cat’s shoulder blades down the ribcage – do this once a month as a quick check.

2. Look For A Defined Waistline

When you view your cat from above, there should be a visible tuck or narrowing behind the ribcage, leading to the hips.

If your Maine Coon looks more like a rectangle or barrel with little indentation, this is a strong sign of being overweight.

3. Watch The Abdomen From The Side

Healthy cats often have a slight tuck in the belly when standing, whereas overweight Maine Coons develop a rounded abdomen, sagging “apron” fat, or a belly that sways when walking.

Some loose skin is normal in large breeds, but a swinging pouch with extra softness indicates fat, not just skin.

4. Monitor Energy Levels

Overweight cats tire more easily and may seem less playful.

If your Maine Coon avoids stairs, struggles to climb cat trees, or gives up chasing toys quickly, it may be because extra pounds are weighing them down.

5. Grooming Difficulties

Cats are usually meticulous groomers. If your Maine Coon starts showing matted fur, greasy patches, or poor coat condition on hard-to-reach areas (belly, back, hips), it could mean they’re too heavy to bend properly.

6. Breathing And Movement Strain

Watch for heavier breathing, wheezing, or even mild panting after short bursts of play. This suggests excess weight is placing strain on the heart and lungs.

Cats shouldn’t pant under normal circumstances.

👉 Pro Tip: Ask your vet for a Body Condition Score (BCS) assessment. This system grades cats on a scale of 1-9, where 5 is ideal. Scores above 6 indicate overweight, while scores of 8-9 indicate obesity.

Common Causes Of Obesity

Maine Coons don’t usually gain weight without reason. Understanding the causes helps you prevent problems before they start.

1. Overfeeding And Free-Feeding

Leaving food out all day encourages constant grazing, even when your cat isn’t hungry. Combined with calorie-dense commercial foods, this quickly adds up

👉 Tip: Use measured portions and feed set meals twice a day.

2. Lack Of Exercise

Indoor-only cats don’t get the same activity as outdoor hunters.

Maine Coons are playful, but if you don’t provide climbing structures or interactive play, they’ll nap the day away.

👉 Tip: Schedule two 10-15 minute play sessions daily using wand toys, laser pointers, or chase games.

3. Spaying/Neutering

Hormonal changes after neutering can reduce metabolism, making cats more prone to weight gain if feeding isn’t adjusted.

👉 Tip: Switch to a slightly lower-calorie diet after neutering and increase activity.

4. Aging And Slowing Metabolism

Senior Maine Coons burn fewer calories and spend more time resting, yet many owners continue feeding them like younger cats.

👉 Tip: Transition older cats to senior diets with controlled calories but high protein.

5. Boredom And Stress

Some cats eat out of boredom or as a stress response. With Maine Coons, long hours alone can lead to emotional overeating.

👉 Tip: Provide puzzle feeders, climbing towers, and interactive toys to stimulate them mentally and physically.

6. Misjudging Their Natural Size

Since Maine Coons are already large, owners often mistake excess weight as “normal”, which delays action to fix the obesity.

👉 Tip: Compare your cat’s growth against age and sex weight charts.

Keeping Maine Coons At A Healthy Weight

Below are some great tips that will help keep your Maine Coon at a healthy weight:

• Weigh regularly. Use a baby scale or weigh yourself with and without the cat. Record results monthly.
• Portion control. Feed according to your cat’s target weight, not their current weight.
• Switch to high-protein diets. Cats thrive on protein. Avoid carb-heavy foods that encourage fat storage.
• Interactive feeding. Puzzle feeders and treat balls slow eating and increase calorie burn.
• Play to their strengths. Maine Coons love climbing – use tall cat trees, shelves, and even wall-mounted perches.
• Gradual changes only. Aim for 1-2% body weight loss per week. Rapid weight loss can cause dangerous liver disease (hepatic lipidosis).
• Vet support. Always consult your vet for tailored advice, especially if your cat is already obese or has other health conditions.

From personal experience, I found switching from the standard Royal Canin urinary dry food to the moderate calorie range really helped Mika’s weight get back on track!

Expected Maine Coon Weight Ranges

• Adult males: 18-22 lbs (8.2-10 kg) according to TICA
• Adult females: 12-15 lbs (5.4-6.8 kg)

Tracking your Maine Coon’s weight against these benchmarks, along with body condition checks, will help you distinguish between “big but healthy” and “dangerously overweight“.

Final Thoughts

Your Maine Coon’s impressive size is part of its charm, but when fat hides beneath all that fur, health risks quickly follow.

By learning how to spot early signs of obesity, understanding the causes, and applying simple daily habits, you can keep your gentle giant healthy, active, and by your side for many years to come.
