Most of us picture cats as sleek, small, and maybe a little aloof. But Kefir? He’s none of that. This massive Maine Coon from Russia is shattering every stereotype you’ve ever had about cats—and winning hearts worldwide while he’s at it. Weighing in at a jaw-dropping 27 pounds, Kefir isn’t just big. He’s majestic.
What’s even more mind-blowing? He’s still growing.
That’s right—Kefir might look like a small mountain of fluff, but he’s technically still a kitten. Maine Coons usually don’t reach their full size until they’re around 3 to 4 years old, and Kefir is still on his way there. His size has caused more than a few double takes from visitors who often mistake him for a dog.

Named after the fermented milk drink by the family’s daughters, Kefir has become more than a pet—he’s a legend in the making.
Kefir’s intelligence is what really sets him apart. His owner, Yuliya, says he behaves more like a polite houseguest than a cat. Picture this: you sit down to dinner, and Kefir pulls up a chair to join. No begging, no chaos—just a giant white cat calmly taking his place at the table like he belongs there.
His manners and awareness give off a weirdly human vibe, making him more of a family member than a pet. And to top it off, he has a talent for opening doors with his powerful paws, as if he owns the place (and honestly, he probably does).
Now here’s where things get even more unusual—Kefir loves water.
Most cats treat water like it’s lava, but not this guy. He enjoys swimming and doesn’t flinch when it’s bath time. Of course, drying him afterward is a different story. With a thick, snowy-white coat, getting him dry can feel like tackling a full load of laundry with a hairdryer.
Still, that’s a small price to pay for such a lovable giant.
Kefir isn’t just famous in his hometown—he’s gone global. His photos and videos have taken over the internet, racking up likes, comments, and shares from cat lovers and curious viewers around the world. People can’t believe his size. They can’t believe his behavior. And they definitely can’t believe he’s not done growing.

Fans are obsessed with his oversized paws, his regal presence, and the way he flops onto Yuliya’s kitchen table like a royal who owns the entire castle.
Kefir’s favorite sleeping spot? Right on top of his human.
Sounds sweet, until you realize 28 pounds of solid cat is basically like having a sack of potatoes land on your chest. According to Yuliya, he’s a total cuddler—loving, affectionate, and always close by. But cuddling with a cat this size isn’t just cozy—it’s a workout.
Still, no one in the household is complaining. When a pet becomes such a source of joy, you adjust to the weight.

It’s not every day you meet a cat that behaves like a dog, swims like a champ, and opens doors like he’s paying rent. But beyond the novelty, Kefir’s story taps into something deeper—our fascination with pets who break the mold.
In a world where we’re surrounded by curated content and filtered photos, Kefir is refreshingly real. He’s quirky. He’s gigantic. And he’s a reminder that nature loves to surprise us.
More than anything, Kefir reminds us that pets are more than animals—they’re personalities. They’re individuals with moods, preferences, and sometimes, very unusual habits. He’s not just big in size—he’s big in character. And that’s what truly makes him unforgettable.

Yuliya never expected her Maine Coon kitten to grow into an internet phenomenon. But by simply being himself—sweet, smart, and larger-than-life—Kefir turned into a symbol of joy, wonder, and the unexpected beauty that pets bring into our lives.
Kefir isn’t just the world’s largest cat—he’s a one-of-a-kind soul with a heart as big as his paws. From lounging at the dinner table to swimming laps in the tub, he’s rewriting the cat rulebook one adorable habit at a time.
And while his size grabs your attention, it’s his personality that truly makes him legendary.
