Cat weight chart is one of the best tools to check if your furry friend is healthy. Whether your cat is a kitten or a senior, knowing the right weight helps you care for them better. With this simple guide, you’ll learn the ideal weight for cats by breed, age, and body type.
Also, you’ll learn how to tell if your cat is underweight, at a healthy weight, or overweight. It’s super easy to understand — no complex terms or vet-only lingo.
Let’s dig in and make sure your cat is happy and healthy!
Why a Cat Weight Chart Is Important
A cat weight chart helps you know if your cat’s weight is right for their age and breed.
You might not notice weight changes just by looking, especially with fluffy cats. A few extra pounds can cause health problems like diabetes, joint pain, or heart issues.
On the other hand, if your cat is too thin, they might not be getting the food and nutrients they need.
Using a cat weight chart can help you:
- Know the average weight for your cat’s breed
- Track their weight as they grow
- Spot problems early
- Talk to your vet with clear info
🐾 Tip: Always weigh your cat at the same time of day and use the same scale for better accuracy.
Cat Weight Chart by Age and Life Stage
🐱 Kitten Weight Chart (0–12 Months)
| Kitten Age | Average Weight (lbs) | Notes |
|---|---|---|
| 0-1 week | 0.2 – 0.3 | Newborns are tiny! |
| 2 weeks | 0.5 – 0.7 | Eyes begin to open |
| 4 weeks | 1 – 1.5 | Starting to walk |
| 8 weeks | 2 – 2.5 | Ready for first shots |
| 12 weeks | 3 – 4 | Growing fast! |
| 6 months | 5 – 6 | Entering teen phase |
| 12 months | 7 – 10 | Almost full-grown |
Kittens grow fast, and their weight can double in just a few weeks. Make sure they eat high-protein food made just for kittens.
🐈 Adult Cat Weight Chart (1–7 Years)
Most adult cats should weigh between 8 to 12 pounds, but it really depends on the breed.
| Cat Breed | Ideal Adult Weight (lbs) |
|---|---|
| Domestic Shorthair | 8 – 10 |
| Siamese | 6 – 10 |
| Maine Coon | 10 – 25 |
| Persian | 7 – 12 |
| Ragdoll | 10 – 20 |
| Sphynx | 6 – 12 |
Keep in mind that male cats often weigh more than females. Use a cat weight chart to track what’s normal for your breed.
😺 Senior Cat Weight Chart (8+ Years)
Older cats may lose weight if they have health issues or a poor diet. An average senior cat still weighs about 8 to 10 pounds, but watch for slow changes.
🐾 Important: A senior cat losing weight could be a sign of dental problems, kidney disease, or thyroid issues.
How to Check If Your Cat Is at a Healthy Weight
You don’t need a vet to guess if your cat is at a good weight. Here’s how to do a quick check:
- Feel Their Ribs
Can you feel the ribs with light pressure? Great!
If they’re too visible, your cat might be underweight.
If you can’t feel them at all, your cat might be overweight.
- Look From the Top
A healthy cat should have a slight waistline.
If they look round like a ball, they may be overweight.
If they’re shaped like a tube, they might be underweight.
- Look From the Side
There should be a tummy tuck near the back legs.
A saggy belly can mean your cat has gained too much.
- Use a Body Condition Score (BCS)
Many vets use a scale from 1 to 9:
1–3: Underweight
4–5: Ideal
6–9: Overweight
You can learn more about BCS from the American Veterinary Medical Association.

What Causes Weight Gain or Loss in Cats?
🐟 Diet
Too many treats or free-feeding can lead to weight gain. On the other hand, a poor diet or not enough calories can cause weight loss.
🧶 Exercise
Indoor cats often move less, which can lead to extra pounds. Try using toys and climbing trees to keep them active.
🩺 Health Issues
Thyroid problems, diabetes, kidney disease, and parasites can all affect your cat’s weight. If changes happen suddenly, see a vet.
🎂 Age
Older cats naturally move less and may lose muscle or gain fat.
