In addition to adopted pets, the Division of Humane Services provides spay and neuter services for feral and barn cats. Run by volunteers one day each month, the Operation Sterile Feral Program through the Pet Adoption Center has treated thousands of feral cats since its introduction in 2003.

Open to St. Charles County residents only, the cats are vaccinated for rabies, treated for parasites and altered so that they can no longer breed. For more information on the Operation Sterile Feral Program or to make an appointment to participate, please call 314-995-9266. Please leave a message if there is no answer, and your call will be returned soon.
