Strangers in Stary Oskol, Russia keep stopping Yulia Minina to ask what breed of dog she’s holding. She isn’t holding a dog.
She’s holding Kefir — a white Maine Coon who went viral in 2022 at 27.5 pounds while he was still a kitten. He’s around 28 pounds now, and his owner says he’s gotten too big to hop onto the bed the way he used to. According to the photos of Kefir draped across her lap, the confusion is fair. He really does look like a small dog wearing a cat’s face.
Here’s the part most people don’t know: Kefir isn’t fully grown. Maine Coons don’t finish until they’re three to five years old, while an ordinary house cat is done at one. The giant on your couch may still be getting bigger.
The largest cat in the room, by design
The Maine Coon is the largest non-hybrid cat breed in the world. Males run 18 to 22 pounds; females, 12 to 15. They are the official state cat of Maine, and the Cat Fanciers’ Association granted the breed Championship status in 1976.
The size shows up in the records. The longest domestic cat alive is a Maine Coon named Barivel, a black tabby from Vigevano, Italy, measured by Guinness at 47.2 inches nose to tail. The all-time record holder was another Maine Coon, Stewie, at 48.5 inches — closer to four feet than to a normal cat, as the running list of the world’s biggest cats shows.
The things only Maine Coon owners understand
The first one is the sound. Maine Coons mostly don’t meow — they chirp and trill, a high warble that seems impossible coming from an animal that size. Owners learn to answer it without thinking.
The second is the water. Most cats flee a running tap. A Maine Coon will sit in the sink, bat at the stream, and follow you into the bathroom to supervise. Their coat is semi-water-resistant, which is part of why the breed will happily wade into a bath that would send any other cat up the curtains.
The third is the shadow. Maine Coons follow their people from room to room and “help” with whatever you’re doing — the breed is so people-oriented that the gentleness, not the size, is what surprises first-time owners. The International Cat Association describes the breed as gentle, intelligent, and famously dog-like in how it bonds.
What the size actually costs
A cat this big is a long commitment to a slow clock. You’re feeding and grooming a growing animal for half a decade before it settles, and that thick double coat needs regular brushing or it mats.
The breed is also predisposed to two health issues worth knowing by name. One is hypertrophic cardiomyopathy, the most common feline heart disease, which Maine Coons carry at higher rates than the average cat. The other is hip dysplasia, unusual in cats but more common in heavy, large-framed breeds. A responsible breeder screens for both, and a vet can catch a heart murmur early — which is exactly why the annual checkup matters more for a Maine Coon than for a six-pound tabby.
Is a Maine Coon right for you?
If you want a cat that ignores you, this is the wrong breed. A Maine Coon will greet you at the door, comment on your phone calls, and take up an unreasonable amount of the bed.
If you want a 22-pound animal that chirps, supervises your shower, and takes five years to reveal its final form — there is nothing else quite like it. Kefir’s owner didn’t set out to raise an internet celebrity. She just got a kitten that never stopped growing.
