Our mission: To help the plight of feral cats on the Greek island of Kalymnos by a massive educational and sterilisation campaign and to advocate for the change of mentalities to support animal welfare.

Since we started this project in August 2021, we have sterilised over 2000 cats on the island.  Learn about our impact here: 

More than 2000 cats have been sterilised on Kalymnos and Telendos since the start of the Kalymnos Cat Project.  Thanks to the generous support of our donors, we were able to sterilise 888 cats in 2023 at a cost of 46040€ in veterinary care in 2023 alone.  To continue the project in 2024 and beyond, further donations will be needed.  We need your support!
