They lounge on fishing boats, peek out from hidden corners, and follow you through winding streets with curious eyes.
On Hydra, it’s the cats who rule!

About Hydra Island
Most visitors hop over just for a day, but once you step onto this car-free island, you’ll wish you could stay forever.
Hydra’s story goes way back. People have been living here since the 4th millennium BCE. Thanks to its perfect spot along ancient trade routes, the island became a major player in maritime trade.
Fast forward to the 18th and 19th centuries, and the island was booming, famous for its shipbuilders, powerful fleet, and wealthy merchant families. Those golden years brought an explosion of culture, art, and architecture, some of which you can still feel around every corner.
One of the coolest things about Hydra? No cars. No motorbikes. Not even a scooter buzzing by. Strict rules keep the island frozen in time.
Over the years, Hydra has drawn some pretty big names.
Sophia Loren fell in love with it while filming Boy on a Dolphin here in the ’50s, and Leonard Cohen bought a house on the island and wrote some of his most famous songs under its spell.
Today, Hydra’s artistic soul is still very much alive, celebrated through gallery shows, music festivals, and open-air theater performances.
Hydra Town is a gorgeous maze of stone alleyways, whitewashed homes, bright blue shutters, and explosions of bougainvillea.
At the heart of it all is the harbor. Fishing boats and luxury yachts bob side by side, and the whole place hums with that relaxed, glamorous energy.
But Hydra’s magic isn’t just about the famous faces or postcard views. It’s the slow mornings, sipping coffee by the sea, the lazy afternoons wandering ancient donkey paths into the hills, and the way the island seems to invite you to breathe deeper, move slower, and actually feel the sun on your face.
Hydra may be small (roughly 20 km long and up to 6 km wide), but it leaves a big impression.
Cats of Hydra
Thousands of cats of various colors and patterns call Hydra island home. Estimates suggest there are well over 2,000 free-roaming cats on the island – possibly even 3,000 to 4,000 during peak kitten season. That means there are more cats than people on Hydra.
With their camera-ready faces and big personalities, they’re often the favorite muses for many traveling photographers.
The harbor cats, in particular, have become iconic figures. They stroll the waterfront like they own it — weaving between tables, posing for photos, and charming treats out of every soft-hearted tourist. Each cat has its own story, its own swagger, and together they bring a playful, unforgettable energy to the island’s sunlit streets.
House cats and store cats
The best fed and happiest cats on the island are, of course, house pets and store cats.
These pampered purr machines are spoiled with regular meals, cozy napping spots, and endless affection from their humans.
You’ll spot them lounging on sunny windowsills, guarding shop entrances like tiny, furry bosses, or curled up in cozy corners without a care in the world.
Harbor cats
The harbor cats have a harder life. However, they are nothing short of survivors. They’ve mastered the art of island life.
Every morning, they hustle down to the docks, ready to greet the fishing boats and charm the fishermen out of a few scraps. Some are brave enough to pull off acrobatic stunts — perching on the narrow railings of private yachts, tightrope-walking for a chance at a fresh catch.
In the quieter moments before sunset, the untamed and independent feral cats come out. During the day, they roam the back alleys and rugged hillsides, but when the sun sets, they prepare for a night of hunting. They are the island’s free spirits, moving with the rhythm of the wild.
Hydra’s Ark
Sure, the cats of Hydra may look like they own the island — but even the toughest feline wanderers sometimes need a helping hand. That’s where Hydra’s Ark comes in.
This local organization is the heart and soul behind the island’s cat care, making sure Hydra’s furry residents stay healthy, safe, and well-fed.
Here’s how Hydra’s Ark is making a real difference:
Bringing vets to the island
There’s one little problem with living on a dreamy car-free island like Hydra: no full-time vet.
But Hydra’s Ark has a clever solution — they bring veterinarians to the island in spurts!
Several times a year, volunteer vets come over to provide much-needed medical care. They perform spay and neuter surgeries, treat injuries, fight off infections, and check up on the overall health of the cats. Without this life-saving service, the stray population would explode, and many cats would suffer without help.
Spay, neuter, and save
Controlling the cat population is key to keeping both the animals and the island in balance.
The main focus of Hydra’s Ark is to trap, neuter, and release stray cats all over the island. Every cat they manage to sterilize means fewer litters of kittens struggling to survive on their own. It’s a humane, effective way to care for the island’s future — both feline and human.
Feeding stations and fresh water
Regular meals aren’t guaranteed for stray cats. However, Hydra’s Ark does its best to change that.
They’ve set up feeding stations and water points around the island to make sure the cats stay healthy and hydrated, especially during the scorching summer months. It’s a simple act that makes a world of difference.
Emergency rescues and daily care
Every day, Hydra’s Ark receives messages from both locals and visitors about cats in need. Their team responds as quickly as possible, assessing each situation and providing the necessary care.
They rescue cats tangled in fishing nets, treat infections, and care for injured or malnourished strays. Often working with limited resources and no permanent veterinary facilities on the island, Hydra’s Ark relies heavily on experience, creativity, and partnerships with visiting veterinarians to ensure that every animal receives attention.
How you can help Hydra’s cats
If you’re visiting Hydra, here’s how you can lend a hand:
-
Leave bowls of fresh water outside shaded areas.
-
Offer small amounts of cat food, but avoid feeding scraps like bones or bread.
- Don’t feed cats near restaurants or hotels: As tempting as it is, feeding cats where people are eating can cause conflicts. Some establishments may react harshly, and in worst cases, it can even lead to the cats being harmed or poisoned. It’s safer — and kinder — to feed them away from busy areas.
-
Report injured or sick cats to Hydra’s Ark through their website or Facebook page.
-
Be gentle and respectful — not all cats are used to being handled.
-
Consider sponsoring a cat through Hydra’s Ark or donating supplies if you can.
- Donate: If these resilient little adventurers have captured your heart, consider donating to Hydra’s Ark. Even a small gift goes a long way toward feeding, treating, and protecting the cats who make Hydra so unforgettable.
And if you fall in love with one of Hydra’s cats — as many visitors do — adoption is possible!
