Feral Cat Sterilizations

Hawaiian Humane Society supports responsible Trap-Neuter-Return-Manage (TNRM), a humane and effective strategy to reduce the number of feral cats in our community and improve their quality of life. 

When people trap, neuter and then return cats to their colonies, the population stabilizes and then decreases as cats live out their natural lives without reproducing. As a result, millions of unwanted kittens have been spared from life on the streets.

Due to limited appointments, this service is for feral cat caregivers those taking care of street cats not cats in your home. We encourage timely drop off and pick ups for this service as holding capacity is limited. Find out more in our Trap-Neuter-Return-Manage (TNRM) brochure.

The Hawaiian Humane Society cares about feral cats in the community. In the last five years, we have helped more than 12,000 feral cats at a cost of over $250,000 for needed sterilizations. This service is funded entirely by charitable gifts.

Our data show that most people who use our feral cat sterilization services spay/neuter between 1 and 5 cats each year. Our $25 charge for sterilization covers some of the costs and makes it possible to offer more appointments and expanded service. This year we are planning on extending our special event mass spay and neuter initiatives island wide. Dates will be announced soon.
