Spay Neuter Assistance Program
Our income-qualifying SNAP program is designed to reduce pet overpopulation by providing low-cost spay/neuter services to the communities we serve.

Who qualifies for SNAP?

To be eligible for SNAP, you must demonstrate financial need by meeting one of the following criteria below: You may be asked to furnish proof on the day of your appointment.
- Forward card or proof of state Medicaid
- Quest card or proof of state food assistance
- Wisconsin Works
- Letter confirming current unemployment compensation
- Social Security letter or statement
- Proof of income demonstrating yearly household income at or below 150% of the poverty line.
To qualify for SNAP, your animal must meet the following criteria:
- Must be between the ages of 3 months and 7 years old.
- Must weigh between 2 pounds and 100 pounds to be eligible for surgery.
- For appointments at the Green Bay, Kenosha, and Racine Campuses: your animal must be up to date on both rabies and distemper (FVRCP for cats and DHPP for dogs) vaccinations at the time of your appointment. You will be asked to furnish proof on the day of your appointment. It is highly recommended that dogs also be up to date on Bordetella as well, although it is not required. Check here for information about our next low-cost vaccine clinic.
Your animal will not be eligible for surgery through the SNAP program if any of the following apply:
- Known or suspected adverse reaction to anesthesia
- History of having a C-section
- Diagnosis of diabetes, FeLV+, currently heartworm+, heart murmur or heart condition, or other serious illness.
Because safety is our priority, these conditions would make your animal ineligible for surgery at WHS. We recommend you follow up with a private veterinarian. There are other medical concerns that may make your animal ineligible for surgery, and this determination can be made any time up to and including the date of surgery. If WHS determines that your animal is ineligible for our services, a full refund will be provided for services paid.

Rescheduling Policy

Out of courtesy to those interested in the SNAP program, we can only permit one canceled or rescheduled appointment. If a second appointment is canceled, it may be at least 6 months before we can schedule another time for your animal to be seen.

Book an Appointment

If you have read the above and meet the qualifications, please use the button below to make an appointment online. Please note: appointments book very quickly due to our limited capacity.
Trap Neuter Return (TNR)
Available in West Allis and Saukville, our TNR program serves community/outdoor feral cats for a nominal fee. Any Wisconsin resident who wants to have a feral cat spayed or neutered, and who agrees to our guidelines, is welcome to participate.

Check out our TNR FAQs for more detailed information!

Important Notes:
- Every cat who receives surgery through this program will be painlessly ear-tipped under anesthesia during their surgery. This is to indicate to concerned parties who spot them outside that this cat has already been spayed or neutered, is not a lost stray, and does not need to be trapped or caught.
- This program is solely for unsocialized, feral cats who cannot live indoors. If a social, easily-handled cat is brought in for TNR services, WHS reserves the right to intake them as a stray (if found within the county) and hold them for the mandatory stray holding period to attempt to reunite them with an owner. If an owner is not found, the animal can begin their journey toward our adoption program. If a social cat is held, we do not charge for TNR services.
- Please note that due to the currently elevated risk of Highly Pathogenic Avian Influenza (HPAI) transmission from birds to cats, we are unable to accommodate surgeries if a cat is from a dairy/poultry farm, has been exposed to a backyard flock, has been exposed to sick/deceased cats, or is showing any neurological symptoms of illness (circling, stumbling, seizures). Thank you for your understanding.
- For the safety of staff and the comfort of the animals, all cats must arrive in a trap.
- Walk-ins are not available. Surgery is by appointment only.
- Drop-off occurs in the morning, and you’ll pick up same-day in the late afternoon.
Barn Cat Spay/Neuter Program
Offered at our Ozaukee Campus, this program is for owned cats who live primarily outside. Any Wisconsin resident who wants to have their barn cat, working cat, or outdoor cat altered is welcome to participate. (If you’re looking to spay or neuter a feral or community cat, please click here for our TNR program instead.)

Barn Cat surgeries are offered by appointment at our Ozaukee Campus, 630 W Dekora St. in Saukville, on Thursdays at 8:30 a.m., and pick-up occurs the same day between 3-5 p.m.

Use the blue button below to book an appointment! On any given day, you’ll be able to see our booking availability for the next 7 days. If all slots are booked, please check back often.

Important Notes
- Since this program is for outdoor cats only, every cat who receives surgery will be painlessly ear-tipped under anesthesia during their surgery. This is to indicate to concerned parties who spot them outside that this cat has already been spayed or neutered, is not a lost stray, and does not need to be trapped or caught.
- Cats must arrive in a carrier of some sort. If your cat is not comfortable with handling and you think you’ll need to trap them, we ask that you only make an appointment once you have already trapped the cat. If a trap was required to catch the cat, they must arrive for their appointment inside the trap, along with a blanket or towel draped on top to reduce their stress during the appointment.
- Please note that due to the currently elevated risk of Highly Pathogenic Avian Influenza (HPAI) transmission from birds to cats, we are unable to accommodate surgeries if a cat is from a dairy/poultry farm, has been exposed to a backyard flock, has been exposed to sick/deceased cats, or is showing any neurological symptoms of illness (circling, stumbling, seizures). Thank you for your understanding.
Provide all cats with water.

Food should be withheld after 10 p.m. the evening prior to surgery, if possible.

On the day of surgery, cats should be brought to their service appointment in secure carriers or live traps.
Full recovery from anesthesia may take up to 24 hours.

Cats must be kept in a safe, warm place away from other animals to recover from surgery. You can use a garage, basement, bathroom, or extra room, as long as it is safe and warm.

Post-surgery Food & Water:
– For adult cats over 5 months of age, offer a little food and water the morning after surgery. If they keep the food down, you can offer more.
– For kittens under 5 months of age, offer food the day of surgery once the kitten is fully awake.
– All cats and kittens should be provided with water once fully alert.

The cat may not urinate or defecate during the first day or two of the holding period.

Cats do not require suture removal after the surgery.

If any complications arise from the surgery, call WHS for advice.
Male cats must be kept indoors for at least 24 hours post-surgery. Do not release them unless the cat is eating and fully alert.

Female cats must be kept indoors for at least 48 hours post-surgery. Do not release them unless the cat is eating and fully alert.

Do not release the cat while they are showing any of these signs:

Typical post-surgical behaviors:
– Deep sleep
– Head bobbing
– Wobbly movements
– Fast breathing
– Shivering

Behaviors of concern:
– Excessive bleeding from the incision
– Inability to lift head by evening
– Difficulty breathing
– Any abnormalities of the surgical site
– Lethargy beyond the first day of recovery.

If any complications arise from the surgery, call WHS for advice.
