About Us


OUR MISSION

The mission of Altered Tails is to provide accessible and affordable spay/neuter solutions for companion animals and free-roaming cats. Our vision is to eliminate euthanasia as a means of population control for companion animals and free-roaming cats.  We are a not-for-profit organization dedicated to providing high quality professional veterinary services and are committed to:

  • Provide affordable spay/neuter service to owners who could not afford to do so otherwise.
  • Offer affordable vaccines and other vital services to owners of companion pets and rescue organizations.
  • Reduce the number of feral cats living in our communities through our Trap, Neuter, Return (TNR) program.
  • Help eliminate euthanasia as a form of population control.
