Feral Cats (TNVR)

Sunshine Foundation’s feral cat programs are designed to help control the feral cat population on St Croix.  Feral cats are not socialized with people and are difficult to tame. They seek out reliable food sources, often congregating around dumpsters, hotels, restaurants, and residential garbage cans. While considered ‘feral’ (formerly domesticated species that have returned to a wild state), they depend on humans for food and water.  Feral cats can multiply exponentially and are a large factor in the overpopulation problem on the island.  Each year hundreds of feral cats are trapped, removed, and euthanized. This does not solve the problem long term as new cats simply fill in the space (known as  the ‘vacuum effect‘).

Sunshine Foundation promotes “TNVR” (Trap, Neuter, Vaccinate, Return) or responsibly trapping, spaying or neutering, and returning the cats to managed colonies where volunteers monitor and feed the colony.  TNR is a humane alternative to euthanasia for managing and reducing feral cat populations, and has a strong track record for success! With the Foundation’s TNR program for feral cats, the felines are tested for Feline Leukemia, spayed or neutered, ear tipped for identification and given an FVRCP booster vaccine that covers common diseases in cats.   All for the low cost of $25.


The Sunshine Foundation TNR Program include:

  • Testing for Feline Leukemia (FeLV) & Feline AIDs (FIV)
  • Vaccination for FVRCP (common contagious feline diseases: Feline rhinotracheitis virus, Calcivirus and Panleukopenia)
  • Spay or neuter surgery
  • Eartipping  a small portion of the tip of a feral cat’s left ear is surgically removed during neuter surgery, to denote that the cat has been neutered and vaccinated. 

Following the surgery, the cat is placed back into the humane trap and once full awakened from anesthesia is released back into the feral cat colony.

To make an appointment for your feral cat please call Sugar Mill Vet Center at  340.718.0002.
