Feral Cats

A feral cat is a domestic cat that has developed a natural fear of humans. Most ferals are the result of abandonment and failure to spay/neuter. Most feral cats are acclimated to their outdoor lifestyle and would not adjust well to an indoor home. Along with other, unowned, free roaming cats, these are collectively known as community cats.

Trap-Neuter-Vaccinate-Return (TNVR) is the process of  trapping feral cats, having them neutered and vaccinated, Ear-tipped  and returning them to their home location. Through TNVR we can greatly reduce the numbers of unwanted feral and stray cats which lowers the intake and euthanasia rates at animal shelters. This saves tax dollars and leaves more space at animal shelters for adoptable cats. TNVR also addresses the public health concern about rabies, and reduces annoying behaviors such as cats fighting and spraying.


Operation Catnip Services

Monthly Clinic:

Operation Catnip is a nonprofit organization that operates a high-volume, no-charge clinic  (funded through donations) where feral and free-roaming unowned cats are spayed/neutered and vaccinated with rabies and distemper. The clinics is run entirely by volunteers (veterinarians, vet technicians and trained lay people) and are capable of sterilizing dozens of cats in a matter of hours.   All cats have the tip of their left ear cropped
which identifies them as sterilized.

*Note: No-charge does not mean” free.” 
Operation Catnip receives no government funding whatsoever and relies solely on donations and grants (if available) to fund our program. Each monthly clinic costs Operation Catnip over $2,000 to run. If we do not receive enough donations, we will be unable to continue offering this very unique and vital community service.

Voucher Program:

In addition, Operation Catnip operates a voucher program where feral and free-roaming unowned cats are sterilized at participating local veterinary clinics. Vouchers are $50.00 per cat and include sterilization, rabies and distemper vaccines, ear crop and pain medication.
