Trap-Neuter-Return (TNR)

is the only method to be proven humane and effective in controlling free-roaming cat population growth


After adequate preparation (feeding points, etc.), colony cats are trapped using humane traps


The captured cats are brought to a partner vet. STERILA's TNR programm also includes deworming, etc.


After recovery from surgery, STERILA returns the feral cats to where they where trapped and supplies them with ongoing access to food and water

Do the right thing

  • Offer dignity – serve as an example – treat all feline beings with respect
  • Tell the world about the power for change that tourists have
  • Do the right thing: TRAP – NEUTER – RETURN (TNR)

  • Become an expert – plan and organize your cat mission well!
  • Hands off: never have a cat sterilized that is very tame, or shows an ear tattoo, a clipped ear (EC cat) or is younger than 6 months; REMEMBER: Attached cats might have been sterilized already (with no visible proof)! Also, from March till November many cats are pregnant. Therefore, in case of doubts, trap/neuter/return a clearly unsterilized MALE cat!

Together we can!


    Thinking of having a stress free holiday in Santorini but still want to help out the strays? 

    We also accept cat food donations via drop off at STERILA HQ in Kamari, Santorini. and help us stock up for our local feeding point network.


    Our rescues specially our orphaned kittens are very happy when receiving warm blanks and toys. Donate via our Wishlist here.


    Our adorable rescued kittens and ready-to-travel cats are waiting to be adopted by a cat loving person and go to their forever home. Contact us for more information.

    You can help STERILA achieve its biggest goal: a cat shelter solution by providing financial support.

    We’re aiming at providing cat homes before the winter torments the strays again, out on the empty streets of Santorini! We need a place for cats during sterilization (temporary stay), for the many kittens found in the garbage, and for cats too young for sterilization. We need a shelter for moms with small kittens and for ill/rehab/injured cats.

THANKS to your financial aid, STERILA can pay for:

  • Vet and medical expenses (spay, neuter, vaccinations, emergencies etc.)
  • Cat food/feeding point network (essential to the TNR-program)
  • Pipeline project: “next generation” (booklets, etc. for kids)
  • Pipeline project: “cat restaurants” (partner hotels/restaurants with own feeding points)


A CAT SHELTER on SANTORINI for feline rescues that can’t make it out on the streets of Santorini!


….to enjoy every single moment a Santorini cat shares with you!...
...Feel good if a cat adopts you.

Feel your heart jump with joy when detecting an EC cat! This fellow friend has a better life thanks to your support! You can see the proof of our work, the EC sign will show it to you! You make it all possible! You actively reduce the suffering of cats on Santorini.

PS: pls DO send us pictures of EC cats

STERLIA is documenting every sterilization, including pictures of each cat before and after OPs. We therefore can track the cats’ history. We truly love receiving pictures of STERILA-cats! Please also tell us when and where you have detected an EC cat. This means so much to us! It is the wonderful reward of hard, expensive, sad and tough TNR-work! It makes us keep on going, stronger!

Lucia + Villy + your STERILA volunteers.
