Feral Cat Altering

The following are services our organization provides with regard to altering and managing a group of unowned feral (wild), unowned free-roaming and unowned community cats.


FFSC provides information on how to trap, offers weekly clinics where cats are altered,  ear tipped, microchipped, vaccinated, treated for parasites and given a wellness check.  We also loan traps and/or can advise on where to rent or buy a trap.

Spay/Neuter Assistance

Every week FFSC holds spay/neuter clinics for unowned feral, free-roaming and community cats (no pet cats). Trapping and transporting is done by the client. FFSC will fix, test, vaccinate, and ear tip the cat(s). The requested donation is $50.00 per cat, but this fee is negotiable depending on the number of cats and the situation. This is not a free clinic. If our clinic is not realistic for the situation, we set the client up with one of our participating veterinarians for the altering procedure. Again a donation of $50.00 per cat is requested for this service. FFSC pays the balance. This $50.00 also includes vaccinations, testing for Feline Leukemia, and ear tipping for identification purposes.
