National Capital Area Spay and Neuter Center
1001 L Street, SE
Washington, DC 20003


The Washington Humane Society (WHS) has committed its staff and resources to solving the overwhelming problem of pet overpopulation and has become the leader in offering safe, affordable, high-volume sterilizations in the DC metropolitan area. The ultimate goal is to reduce the number of unwanted animals entering our adoption centers. The cost of each and every surgery is subsidized by WHS.

Appointments are required for spay/neuter surgery
Services are provided to the general public in the DC metro area, but because the National Capital Area Spay & Neuter Center also serves many area shelters and rescue groups, as well as feral cats, demand for appointments is high and should be scheduled one to two weeks in advance. Appointment slots for the public are offered Monday through Thursday.  

Surgical Requirements and Recommendations

  • Animals must be at least four-months-old and weigh at least two pounds.
  • For their own protection against contagious diseases, it is strongly recommended that all dogs and cats be current on distemper and rabies vaccinations prior to scheduling a surgical appointment. 
  • Pre-operative blood work is strongly recommended for pets over six years of age.
  • Pets 10-years-old and older do not qualify for services through the Center.
  • All dogs must be leashed and all cats and rabbits must be in a secure enclosed carrier prior to entering the Center.

If you have any further questions regarding pre-surgical requirements, you can visit the appointment scheduling page, email snc@washhumane.org or call 202-88-ALTER (202-882-5837).

What is the WHS National Capital Area Spay & Neuter Center?

Low-Cost and High-Quality: Can they go hand-in-hand?

The National Capital Area Spay & Neuter Center is a non-profit, high-volume, high-quality veterinary clinic performing low cost spays and neuters for cats, dogs, and rabbits. Whereas a traditional veterinary hospital must be prepared to provide a wide variety of services each day, a specialized spay and neuter clinic can focus its efforts entirely on perfecting and streamlining only one task: sterilization (we also provide vaccinations and other basic ancillary treatments). The need for extraordinary efficiency in every aspect of a successful high-volume clinic means employing a motivated staff that's willing to work as a team, communicates very well, and has a dedication to the purpose of the clinic; combating pet overpopulation and reducing the numbers of animals born into homelessness or surrendered to area shelters. The National Capital Area Spay & Neuter Center employs such a talented and dedicated team!

The National Capital Area Spay & Neuter Center medical team expects excellence from itself and strives to provide the very best care with each surgery performed. Our staff works daily with the passion of ending the cycle of pet overpopulation and companion animal’s homelessness. Despite the emphasis on speed, the medical team at the National Capital Area Spay & Neuter Center recognizes the vital importance of providing thorough and safe care. Speed may be vital, but safety is imperative. Our veterinarians are licensed and accredited. Our assistants and technicians are dedicated professionals. We handle many surgeries each day but will not sacrifice quality nor the proper care and attention that your dog or cat requires and deserves. While we are a high volume clinic, we treat each animal as if they were one of ours.

High-Volume Spay/Neuter Clinics Impact Pet Overpopulation

High-volume spay/neuter clinics play an important role in reducing pet overpopulation in the communities they serve. Although it's difficult to quantify the exact impact these clinics have made on dog and cat overpopulation, the sheer volume of animals these clinics have prevented from reproducing has undoubtedly had a tremendous effect on the pet overpopulation crisis. The National Capital Area Spay & Neuter Center partners with regional animal shelters to support them in their mission to reach 100% pre-adoption spay and neuter for all of their shelter animals heading into forever homes.

Every animal deserves to be wanted
Sadly, thousands of animals are born each year in our area only to end up at already crowded adoption centers or abandoned on the streets. Sterilization is the only method available to end animal overpopulation. Please help us end the overpopulation problem by supporting the work of our WHS National Capital Area Spay & Neuter Center. A gift of $60 will prevent one cat from adding to the thousands of strays and ferals in our community. $120 will end the cycle of backyard breeding for one dog. Please visit our DONATIONS PAGE to help us move forward in our mission to help stem the tide of homeless animals! Together we will make a difference!

Regional Participation is the Solution
In response to the overwhelming agreement about the area’s need for affordable sterilization, WHS expanded its surgical facility to not only support our own adoption center animals and animals owned by the general public, but to also partner with area groups in need of support with their own localized spay/neuter initiatives. Area rescues now utilizing our services to reach their goal of 100% pre-adoption sterilization include:

  • Tails High Cat Rescue
  • Homeward Trails Animal Rescue
  • Operation Paws For Homes Rescue
  • Dog World Rescue, Inc.

If you work with a local animal shelter or rescue group, please contact Sara Spendelow at sspendelow@washhumane.org, or by calling 202-88-ALTER X 103 for additional details about how you can get involved.
