I’ll be honest. The first time I saw a Korat and a Russian Blue in the same room, I thought someone was pranking me.
Same silver coat and green eyes. Same “I’m too elegant for this” face.
Then I spent a weekend with each. And wow. Night and day.
One followed me to the bathroom and stared at me like, “You okay?” The other sat across the room, watched me, and only came over once I proved I was worthy.
If you’re choosing between a Korat and a Russian Blue, looks won’t help you. Personality will. Here’s the real breakdown from someone who’s fostered both.
The Quick Take
- Pick Korat if you want a loyal, people-focused cat that bonds to you like glue. You work from home, and you are like a quiet, gentle shadow.
- Pick Russian Blue if you want a calm, independent cat that’s polite, clean, and low-drama. You like peace but not clinginess.
Both are stunning. Both live long. But they want very different things from you.
1. History: Good Luck Charm vs Russian Aristocrat
Korat
In Thailand, they call the Korat “Si-Sawat.” It means “good luck.” For hundreds of years, people gave Korats in pairs to newlyweds as a blessing for prosperity.
They’re an ancient natural breed. No human mixed anything in. That’s why they still look exactly like temple drawings from 600 years ago. They didn’t come to the US until the 1950s, and even now they’re rare. TICA only registers a few hundred a year.
That rarity matters. Korats know they’re special, and they act like it—in a shy, watchful way.
Russian Blue
The Russian Blue story is murky. Most think they came from the port of Arkhangelsk in northern Russia. Sailors brought them to England in the 1860s. Their thick double coat helped them survive freezing docks.
By the early 1900s, they were favorites of Russian aristocracy and, later, British royalty. That tracks. They carry themselves like they own the place, but quietly.
VCA notes they’re one of the oldest natural breeds in Europe. No weird breeding, just time and cold weather.
The difference: Korat = temple cat bred for luck. Russian Blue = a dock cat bred for survival.
2. Looks: Heart vs Wedge
Side by side, people mix them up. Here’s how to tell:
Korat
- Coat: Short, single layer, silver with a halo effect. Feels like water running off it.
- Eyes: Huge, round, luminous green. Like peridot.
- Face: Heart-shaped. Seriously. Look at the brow and chin.
- Body: Medium, but dense. 8-10lbs that feels like 15lbs. Muscular.
They look alert and soft at the same time. Like a little panther made of moonlight.
Russian Blue
- Coat: Thick, double layer, plush. Silver tipping makes them shimmer. Feels like velvet.
- Eyes: Almond-shaped, bright green, distant-looking.
- Face: Wedge-shaped. Long nose, high cheekbones.
- Body: Long, lean, elegant, 7-12lbs with long legs.
They look regal. If Korats are ballerinas, Russian Blues are models on a runway.

3. Temperament: Velcro vs Dignified
This is where they split. And it’s huge.
Korat Personality
Korats pick a person. And that’s it.
My foster Korat, named Chai, wouldn’t leave me alone. Not in a needy way. He just had to be in whatever room I was in. Cooking? Sitting on the counter watching. Working? On the desk, not on the keyboard, just… watching.
They’re sensitive. Loud voices, big parties, new people — it stresses them out. But with their person, they’re incredibly sweet. They’ll sleep on your chest and purr like a motor.
Key traits:
- Affection: High, but only for trusted people
- Social: Shy with strangers. It takes weeks to warm up
- Energy: Moderate. Loves interactive play but hates chaos
They’re on our list of friendliest cat breeds but with an asterisk: friendly to *you*.
Russian Blue Personality
Russian Blues are the opposite of clingy. And that’s why people love them.
They’re polite. They won’t meow for food at 3 am. They won’t sit on your laptop. They’ll sit 3 feet away and observe. When they do come for pets, it’s brief and meaningful.
They’re also brilliant. Not “do tricks” smart like a Siamese. “Figure out how to open the treat cabinet” is smart. They hate change. New furniture, new schedule, new baby — give them 2 weeks to adjust.
Key traits:
- Affection: Moderate to high, but on their terms
- Social: Shy at first, deeply loyal to family
- Energy: Low to moderate. Likes routine play
Real talk: Want a shadow? Korat. Want a roommate who pays rent in peace? Russian Blue.
4. Grooming: 5 Minutes vs 10 Minutes
Good news: neither is high maintenance.
Korat
Single coat = easy. Once a week with a rubber brush, and you’re done. They barely shed because there’s no undercoat.
- Brushing: 1x per week
- Bathing: Rarely
- Shedding: Very low
Russian Blue
A double coat means a bit more work. Twice a week in spring and fall, or you’ll find tumbleweeds. The rest of the year, once a week is fine.
- Brushing: 2x per week
- Bathing: Only if dirty
- Shedding: Moderate, seasonal
Their coat is wash-and-wear, though. It doesn’t mat. If you’re comparing short vs. long hair, both of these are the easy end.
5. Health and Lifespan
Both are healthy breeds, but there are caveats.
Korat
Because the gene pool is small, you have to be careful. The big ones are GM1 and GM2 gangliosidosis. It’s a fatal neurological disease. Reputable breeders test for it.
Ask for DNA testing paperwork. If a breeder can’t provide it, walk away. Lifespan is 14-17 years with good care.
Russian Blue
They’re tanks. Very few genetic issues. The 2 things to watch:
- Weight gain: They love food and hate exercise. Get fat fast.
- Bladder issues: If they don’t drink enough water.
Lifespan: 15-20 years. I’ve met 19-year-old Russian Blue cats that still acted like 5-year-olds. AVMA recommends annual bloodwork after age 7 for any senior cat.
6. Intelligence and Trainability
Both are smart. They just use it differently.
Korat
Emotional intelligence. They read you. Bad day? Chai would come sit and stare until I pet him.
They learn routines fast. Clicker training works great if it’s 5 minutes and fun. They get bored and quit if it’s repetitive. Puzzle feeders, fetch, hiding treats — they love it.
- Learning speed: Fast
- Best training: Short, positive, with you
Russian Blue
Problem-solving intelligence. They watch, they wait, they execute.
Mine learned to open doors in 3 days. They also learn your schedule better than you do. Feed at 7? They’ll be at the bowl at 6:58.
They respond best to calm, consistent training with treats. Yelling doesn’t work. They’ll just leave the room.
- Learning speed: Average to fast
- Best training: Routine-based, treat-driven
Both are on our smartest cat breeds list, but for different reasons.
7. Living Situation: Apartment vs Apartment
Good news: both are perfect apartment cats.
Korat
They need quiet. They need you. If you’re gone 10 hours and come home to loud music and friends, they’ll hide.
Best home: calm, 1-2 people, work from home. They do NOT like being outside. Because they’re rare and trusting, they could get stolen.
Russian Blue
More flexible. They handle a 9-5 better as long as the routine is consistent. They love window perches and quiet corners.
They’re also great with other calm pets. Introduce slowly. They don’t like hyper dogs.
Both should be indoor cats. Their coats and personalities aren’t built for the street.
8. Cost and Finding One
Neither is a shelter cat. Both come from dedicated breeders.
Korat
$800-$1,800. Because they’re rare, waitlists are long. Only buy from someone who does GM1/GM2 testing.
Russian Blue
$600-$1,200. More common, so easier to find. Still, ask for health screening.
Red flag for both: “silver” cats with yellow eyes. True Korats and Russians have green eyes. And avoid anyone advertising “mini” versions.
Final Thoughts: Which One Is You?
After fostering both, here’s how I break it down:
Get a Korat if you want a cat that chooses you and only you. Someone who will be your quiet shadow, who hates chaos, and who gives deep, loyal love. They’re like the friend who texts “you good?” when you’re quiet.
Get a Russian Blue if you want elegance without drama. A cat that respects your space, keeps the house peaceful, and shows love in small, perfect moments. They’re like the friend who brings soup when you’re sick and doesn’t make a big deal about it.
Neither is better. They’re just different kinds of love. Both will give you 15+ years of silver, green-eyed magic.
Just don’t pick based on looks. Pick based on how much attention you want to give back.
