Spay/Neuter Services

Services typically available in Winter Months

In the summer months we are engaged throughout Western Montana providing much needed spay/neuter and vaccination services to under-resourced shelters and communites around us. In the winter months when travel is more difficult, we offer increased services to under-resourced populations in our immediate Missoula community.

Our goal is to improve pet health and decrease the number of homeless pets in our community by providing affordable access to spay and neuter services for pet owners who would otherwise be unable to afford these procedures in a regular vet clinic. If we have the capacity to offer services through the summer months, we will announce those dates here.

Before you schedule:

  • Animal(s) are scheduled to be dropped off between 8:15AM and 8:45AM the day of surgery and picked up between 4:30PM and 5:00PM the same day. We cannot hold animals overnight.

  • Animals cannot have food, treats, or snacks after midnight the night before surgery. Water is fine.

  • If your pet is sick we cannot perform surgery on them. Please call the shelter at 406-549-3934 and leave a message to reschedule.

  • If you cannot make it to the appointment you scheduled, please email the clinic coordinator at or call the shelter at 406-549-3934 and leave a message. Any no-call/no-shows will not receive a refund and will have to register again for a different surgery appointment as they become available.

  • All cats must come in a secure carrier and all dogs must come on a leash (if you do not have a leash, ask staff for one before getting your dog out of your car).

  • For your pet's safety, as well as the safety of our other patients and pets at the shelter, we do require all cats and dogs to be either up-to-date or receive vaccines at time of service. Proof of prior vaccination can be uploaded/emailed to

  • Please remember, our clinic is NOT a fully functioning vet clinic. Our goal is to increase access to low-cost services in Missoula and one of the ways we can lower the costs of services is by automating our software and not retaining paid reception staff. Our staff are working hard and passionately to provide these services. Please be patient and kind.

Spay/Neuter Assistance for Feral Cat Colonies

Trap-Neuter-Return (TNR) is a program for feral cats designed to reduce the stray and feral cat populations in the community. TNR is widely accepted as the most humane and effective way of managing and reducing free roaming cat populations.

Currently this program is very limited by a national veterinarian shortage and funding. 

To apply for assistance with feral cats, please email

Visit Alley Cat Allies or ASPCA for more information on feral cats or to learn more about the benefits of TNR.

Vaccination Clinics

Please check back in Winter of 2022 for vaccine clinics in Missoula

We will be sure to announce any upcoming Missoula clinics here on our website and on our Facebook and Instagram pages. 

Petworks Care Clinics are made possible by The Max & Betty Swanson Foundation.

Veterinary Financial Assistance

Finding Help for Veterinary Bills

  • Look into national and regional organizations who may be able to help. HSUS and Best Friends offer resource pages with lists of organizations providing information about paying veterinary bills and veterinary assistance funds.
  • Consider crowdfunding through websites like GoFundMe or Waggle.
  • Consider temporary credit from resources like CareCredit or Scratchpay.

Nandi Wishcamper Medical Assistance Fund

The Humane Society of Western Montana’s Nandi Wishcamper Veterinary Assistance Fund assists families and individuals undergoing financial stress who need help caring for their pet’s medical needs or paying medical bills. Examples of procedures covered include: diagnostic testing, x-rays, lab work, surgical procedures and grooming. We are unable to provide assistance for on-going, maintenance care of a diagnosed issue.

To apply for financial assistance through our Nandi Wishcamper Medical Assistance Fund, please fill out the application form. In order to process your application, we also need an estimate or invoice from the treating veterinarian before we can determine any contributions. Invoices/estimates can be emailed to, dropped off in person at the shelter or mailed. Please note that we are only able to submit financial assistance to veterinarians; we are not able to reimburse individuals at this time. Also, please be aware that we have very limited funding and are often limited to contributing to pets residing in or near the Missoula area. As funds are available, we offer one-time, partial assistance for diagnostic exams and treatment.
