Decoding Maine Coon Kitten Growth: A Weight Chart
Understanding how your Maine Coon kitten is developing is crucial. Many owners are keen to track their kitten’s growth, comparing them to others and ensuring they are on a healthy path. We’ve kept detailed records on the weights of Maine Coon kittens from various litters in our cattery, and we’re happy to share this data with you.
It’s important to remember that every kitten is unique, and weight can fluctuate. This table should serve as a general guideline, not a strict rulebook. If you have any concerns about your kitten’s growth, always consult with a veterinarian.
| Age of Kitten | Average Weight of Male Kittens | Average Weight of Female Kittens |
|---|---|---|
| 1 day old | 90-150 grams / 0.2-0.33 lbs | 90-150 grams / 0.2-0.33 lbs |
| 1 week old | 150-250 grams / 0.33-0.55 lbs | 150-250 grams / 0.33-0.55 lbs |
| 2 weeks old | 270-350 grams / 0.6-0.77 lbs | 270-350 grams / 0.6-0.77 lbs |
| 3 weeks old | 400-450 grams / 0.88-0.99 lbs | 400-450 grams / 0.88-0.99 lbs |
| 1 month old | 500-600 grams / 1.1-1.32 lbs | 450-550 grams / 0.99-1.2 lbs |
| 2 months old | 1200-1500 grams / 2.6-3.3 lbs | 1100-1300 grams / 2.4-2.9 lbs |
| 3 months old | 2000-2300 grams / 4.4-5 lbs | 1600-2000 grams / 3.5-4.4 lbs |
| 4 months old | 2.8-3.5 kg / 6-7.7 lbs | 2.4-3.0 kg / 5.3-6.6 lbs |
Weight at Birth: Maine Coon kittens typically weigh between 100 to 150 grams (0.22-0.33 lbs) at birth. Interestingly, the size of the litter can influence individual kitten weight. Larger litters often mean slightly smaller kittens at birth.
Early Days: It’s common for kittens to lose a small amount of weight (5-8 grams or 0.022 lbs) in the first 24 hours after birth. However, a healthy kitten should gain 5-10 grams (0.022 lbs) daily after that initial period. Consistent weight loss or failure to gain weight is a cause for concern and warrants a vet visit. It could indicate insufficient milk intake or underlying health issues.

Maine Coon Size as They Mature: Beyond Kittenhood
After 4 months, Maine Coon kittens grow at varying rates, even within the same litter. On average, expect your kitten to gain approximately 1.1 to 2.2 lbs (500 to 1000 grams) per month.
While some kittens might reach their adult weight by 7-9 months, others, particularly males, can continue to grow for up to 3-5 years! Don’t be surprised if your Maine Coon is still filling out well into their third year. If a cat is around 9.9 lbs (4.5 kg) at 10 months, significant further weight gain is less likely.
Adult Maine Coon Size and Weight:
- Adult Females: Typically weigh between 8.8-13.2 lbs (4-6 kg).
- Adult Males: Generally weigh between 11-19 lbs (5-9 kg), but larger males can exceed this.
It’s worth noting that Maine Coons are not just about weight; their overall size is also impressive. They are long-bodied cats with substantial bone structure, contributing to their grand appearance.
Factors Influencing Maine Coon Cat Size
Several factors play a crucial role in determining the final size of your Maine Coon:
1. Genetics and Parental Size:
Genetics are the most significant determinant of size. If both parents are large Maine Coons, it’s highly probable their kittens will also grow to be large. However, genetics are complex, and even kittens from smaller parents can sometimes surprise you with their size.
2. Gender:
Maine Coons exhibit sexual dimorphism, meaning males are typically larger than females. This difference is generally quite pronounced in this breed. While most males will outweigh females, there are always exceptions. For instance, our female Maine Coon, Mafia, tips the scales at an impressive 18 lbs (8 kg), exceeding the average weight for females.
3. Nutrition:
Proper nutrition is vital for healthy growth. A diet lacking in high-quality protein can hinder a kitten’s development, potentially resulting in a smaller adult size. Ensure your Maine Coon kitten receives a diet formulated for growth, rich in protein to support their muscular development.
4. Breed Purity:
Breed purity also plays a role. Mixing Maine Coons with other breeds can impact their size and overall breed characteristics. Responsible breeders focus on preserving the natural traits of the Maine Coon, including their impressive size and distinctive temperament.
Is My Maine Coon the Right Size?
Remember, the provided weight ranges are averages. Don’t be overly concerned if your Maine Coon is slightly outside these ranges. Focus on ensuring your cat is healthy, active, and eating well. Consult your veterinarian if you have any concerns about your Maine Coon’s growth or weight.
Ultimately, while their size is captivating, the true charm of the Maine Coon lies in their wonderful personality. Their friendly, gentle, and playful nature makes them fantastic companions, regardless of whether they are the biggest cat on the block!
