CatFriends operates as an ALL volunteer organization. We hold public clinics at least once a month. An appointment is needed & can be made through our link located on the spay & neuter clinics tab. Please visit the spay & neuter clinic tab for more info. Our mass-trapping mode of operation includes training colony caretakers in humane animal trapping, and, with the caretaker's assistance, conducting mass trappings in an effort to sterilize the majority of the cats under their supervision. Once the bulk of the cats have been sterilized, the caretaker must complete the process by trapping and altering the few remaining felines.

CatFriends started in 1999 with a group of people interested in trying to humanely decrease the numbers of abandoned and feral cats on O'ahu. In 2002 we became a non-profit 501(c)(3) organization.

Because we operate as an all-volunteer organization, 100 percent of donations to CatFriends are applied towards the costs of humane traps and bait, feline transportation to and from the trapping location, fees associated with microchipping/sterilization, and medical attention felines may require to bring them back to health.

Killing animals simply because they exist is the antithesis of compassion. And, euthanizing community cats creates what is known as the vacuum effect. "Feral cats establish territories based on availability of food sources and shelter. When the cats are removed from this environment, more cats quickly move in to take advantage of those resources. These new unsterilized cats will breed prolifically. The vacuum effect has been documented around the world." [Alley Cat Allies: "Get Informed: Discover the Truth About the Vacuum Effect"]

No. We require all cats, friendly or feral, to be in a humane cat trap. If you do not have access to a humane cat trap, we offer trap rentals through our trap loan program. You must be already registered for a clinic to request a trap. This is to ensure the safety of our volunteers because cats can become fearful & anxious in new environments.

Our services are strictly for outdoor, free-roaming cats. We recommend you bring your pet cat to a veterinarian for a clean bill of health.

We do not charge a fee for our services; however, donations are accepted & greatly appreciated to continue our efforts.

We are not open daily & do not accept walk-ins on clinic day. Please visit our Spay & Neuter services tab to view upcoming clinic dates & register.

We are located on Kunia Road, around 2.5mi south of Schofield Army Base. You will receive an email at least 48 hours prior to your appointment. This email contains our address (with specific directions to our clinic), instructions for the cat, & your drop-off time.

Yes. You will be given a time for pick-up at the time of your designated drop-off. Pick-up times depend on how many cats show that clinic day.

You should never attempt to trap a cat without an appointment already scheduled. This causes stress for the cat and it makes the cat more difficult to trap again when an appointment is obtained.

After clinic registration is closed, we only make exceptions for pregnant cats. Please contact us immediately if you find a pregnant cat after registration is full. (808)226-4561
