Why do some cats have clipped hears?

As you walk around the island you will see cats that have their ear clipped. This is an international sign that indicates these cats have been sterilized. Our neuter/spay programs are made possible by the generosity of visitors and donors to HydraArk here on the Island of Hydra. These cats are sterilized to help control the cat population of the island and to keep existing cats free from disease and fighting.

Sterilizing does not harm the street cats in any way. On the contrary, sterilized cats live longer and healthier and will still hunt mice and rats so as to keep this island a better place free from vermin.
