Newborn Maine Coon Kittens: The First Weeks

Published: August 10, 2025 • Updated: February 3, 2026

What are newborn Maine Coons really like?  It can be hard to picture your big, fluffy Coonie fitting in the palm of your hand - but every one of them started out that tiny. Soft, squirmy, and surprisingly similar to any other newborn kitten.

If you've just found yourself caring for newborn kittens, or you're staring at a fresh litter wondering what you're looking at, you're not alone.

The first days can bring a mix of excitement, curiosity, and a fair amount of uncertainty.

Let's talk about what's normal in those earliest weeks, what doesn't show up yet, and why newborn kittens don't tell you much about breed at first - even when Maine Coon traits run strong later on.

What Newborn Kittens Can (and Can't) Tell You About Breed

At birth, all kittens look remarkably alike, regardless of breed. Newborn kittens are built for one thing: staying warm, nursing, and surviving those first fragile days.

Those characteristics emerge gradually, often over months, not days.

This is why appearance alone can’t confirm breed at the newborn stage. A kitten's early look reflects age and development, not lineage.

If you're caring for a litter and trying to make sense of what you're seeing, this is important to know: nothing about a newborn's size, color, or facial shape can reliably identify breed.

That clarity comes later (or through documented lineage) not from first-week photos.

How Small Are We Talking?

Despite their reputation as gentle giants, newborn Maine Coons are surprisingly small.

They usually weigh in at 85-115 grams (about 3-4 ounces). At birth, their eyes are closed, ears are folded, and their fur is soft but still "kitten short."

Life in the First Days

During this stage, breeders play a crucial role.

Newborn Maine Coons can't regulate their body temperature, so they rely on their mother's warmth (and sometimes a heat source in the nest).

They nurse frequently, usually every 1-2 hours, and their little round bellies are the best sign that they're getting enough.

About Nursing

Most newborn Maine Coons instinctively find their way to a nipple within minutes of birth, guided by the warmth of their mother's belly, the scent of milk, and her gentle nudging. However, not every kitten gets it right away.

In very large litters (Maine Coons can have 6–8+ kittens), competition for the prime nipples is fierce, with the strongest kittens grabbing the best spots, usually those closest to the mother’s head, where it’s warmer and safer.

The "Runt of the Litter"

You've probably heard the term "runt of the litter." It's a real thing, but often misunderstood.

In cat litters, the runt isn't necessarily the youngest or genetically different; it's simply the smallest kitten at birth.

Sometimes, the runt's size difference is due to being positioned differently in the womb, which results in less access to nutrients. Other times, it's simply natural variation.

What makes a runt stand out?

They can be visibly smaller, weaker, or slower to compete for a nipple. While most will catch up just fine, some need extra help, especially in those first few days.

How breeders help runts:

• Monitoring weight daily: Weighing twice a day for the first week to make sure the kitten is gaining steadily.

• Supplemental feeding: Bottle or syringe-feeding kitten milk replacer if the runt can’t nurse enough.

• Nipple access: Placing the runt at a back nipple (where milk flow is strongest) and holding them there so they don’t get pushed off by bigger siblings.

• Warmth and energy: Ensuring the kitten is warm before feeding, as chilled kittens can’t digest milk well.

Most runts thrive with a little TLC. And in some cases, they grow into the biggest, most robust cat of the bunch! Starting small doesn’t always mean staying small.

One sweet thing about runts is that all that early hands-on care often makes them extra people-focused.

Runts often spend more time in human hands because they need more frequent feedings and warmth.

This can create a deep bond, and many owners find their runt follows them like a shadow or loves snuggling more than their littermates.

Changes You Can't See in Photos

Even in that first week, so much is happening:

Coat Color Changes

One thing that surprises many people when kittens are first born is how unfinished they look, especially when it comes to color.

Newborn kittens are often darker, lighter, or more "blurred" in pattern than they'll be later.

Tabby markings can be faint, contrast can be low, and some colors won't fully show themselves for weeks, or even months. That's completely normal.

Coat color, contrast, and pattern definition develop gradually as kittens grow, their fur lengthens, and pigment settles in. What you see in the first days is just the starting point, not the final picture.

Smoke kittens are a classic example. Newborn smokes often look solid because their fur is extremely short and flat, hiding the pale undercoat that defines the pattern.

As the coat grows and begins to move, that silver or white underlayer becomes visible. Until then, there’s often nothing obvious to see.

Silver tabbies can also look dark or low-contrast at birth, with striping that sharpens over time. Red kittens may appear pale at first and deepen dramatically as pigment develops.

Even solid versus smoke coats, like black versus black smoke or blue versus blue smoke, can be hard to distinguish early on.

It's only as kittens grow into their fur that those hidden colors and patterns finally reveal themselves, which is why breeders often wait before making final color calls.

For Those on the Waitlist

Breeders often wait until kittens are several weeks old before visitors are welcome, partly for health reasons and partly because newborn Maine Coons need time to grow before handling.

But knowing what’s happening now - the tiny squeaks, the careful weighing, the watchful mama - can make the wait even more exciting.

Whether your Coonie is 12 weeks or 12 years old, it’s sweet to picture that once upon a time, they fit in the palm of a hand, with a little button nose and a mew you could barely hear.
