A HUMANE, ISLAND-WIDE SOLUTION
Trap-Neuter-Vaccinate-Return (TNVR) is the core of RCC's strategy to reduce St. Croix's free-roaming cat population humanely. Community cats are trapped, sterilized, vaccinated, ear-tipped for identification, and returned to the territory they already know.
When TNVR is done consistently and paired with responsible colony management, fewer kittens are born, colonies become smaller and more stable, and the cats already living in our communities are healthier.
NEED TNVR HELP?
RCC provides TNVR assistance for St. Croix community members who need help accessing or affording sterilization for free-roaming cats. Commercial properties and businesses are served through our separate fee-based Business Services program.
HOW TNVR WORKS
WHY RETURN CATS?
Removing cats from an established territory does not address the conditions that attracted them there. Food, shelter and other resources remain, and new unsterilized cats can move into the open territory and begin reproducing.
TNVR interrupts that cycle. Sterilized cats retain their territory without producing new litters, while caregivers can identify and address newcomers before another breeding cycle begins.
AFTER TNVR
Successful TNVR does not end at surgery. Stable colonies need responsible feeding, observation and follow-up. New cats should be identified quickly and sterilized before they reproduce, and sick or injured cats may need veterinary care or rescue.
That is why TNVR connects directly to RCC's Food for Ferals and Distributed Sanctuary work.
LOOK FOR THE EAR TIP
A cleanly tipped ear is the universal visual marker of a community cat who has already been sterilized. It allows trappers, caregivers and veterinary teams to recognize a TNVRed cat from a distance and avoid unnecessary retrapping and surgery.
When you see an ear-tipped cat in a managed colony, you are seeing TNVR at work.
RESPONSIBLE COLONY CARE
FEEDING AND TNVR GO TOGETHER
Feeding community cats helps keep them healthy and makes colonies easier to monitor—but feeding alone does not control population growth. Every regularly fed colony should also have an ongoing plan to sterilize newcomers before they reproduce.
That is what we mean by “Feeding is breeding unless you’re snipping and tipping.” Consistent food, TNVR and attentive caregivers work together to create healthy, stable colonies that shrink over time.
LEARN ABOUT FOOD FOR FERALSVETERINARY CAPACITY MATTERS
TNVR works best when surgery can be provided consistently and at high volume. From late April 2022 through late October 2023, RCC helped organize and support high-volume spay/neuter clinics operating only two to three days per month. In that limited clinic time, 1,075 St. Croix community cats were sterilized, vaccinated and returned.
After that high-volume surgical capacity was no longer available, access to surgery became the limiting factor. RCC continued trapping and funding TNVR wherever appointments were available, but the number of cats we could reach was constrained by island veterinary capacity.
HIGH-VOLUME TNVR RETURNS IN Q4 2026
Beginning in the fourth quarter of 2026, high-volume surgical capacity is becoming available again on St. Croix. RCC expects access to approximately 4–8 high-volume clinic days per month during periods when our veterinary partner is on island, while additional veterinary partnerships are being explored to expand that capacity further.
This creates an opportunity to move beyond addressing cat overpopulation one case at a time. With sustained high-volume TNVR and responsible colony management, our goal is to reach enough of St. Croix's community-cat population to create a measurable, lasting decline.
Clinic capacity and scheduling can change as veterinary availability changes; RCC will report actual results as the expanded program develops.
WE KNOW HIGH-VOLUME TNVR CAN WORK. NOW WE'RE READY TO SCALE UP.
Help us sterilize more cats, stabilize more colonies and build a healthier future for St. Croix.
