Low-Cost Spay/Neuter Services for Dogs & Cats

Humboldt Spay/Neuter Clinic provides high-quality, affordable spay and neuter services to help manage pet overpopulation and prevent unwanted litters. By spaying and neutering your pets, you can prevent excessive reproduction—a major factor in the U.S. overpopulation crisis.

Benefits

​Choosing to spay or neuter your pet not only helps control the pet population but also offers numerous benefits to your pet's health and behavior: • Lessens the likelihood of fighting and spraying, which are often linked to territorial instincts. • Decreases the tendency to roam, keeping your pet safer at home. • Neutered animals are typically easier to train and more docile, as they are not driven by reproductive instincts. • Significantly reduces the risk of mammary, testicular, and uterine cancers. • Eliminates the risk of life-threatening infections such as pyometra. We’re here to help you take care of your pet and make the best choices for their health and your peace of mind. Join us in making a difference in Humboldt’s pet population.

Disclaimers

For surgery and exams: • ​Weight limit for dog spay/neuter - 100 pounds  • Age limit for dog spay/neuter - 5 years • We cannot spay/neuter brachycephalic animals (breeds with short, flattened faces) • Rabies vaccination is required for all dogs. Please bring a valid rabies certificate to your appointment, or we can administer the vaccine at the time of surgery.

dark vaccines
Vaccines... $21

​​• Rabies: All dogs over four months of age residing in Humboldt County are required to have a current rabies vaccination for their protection as well as protection for our community. Dogs with current rabies vaccinations are eligible for a dog license, the purchase of which is required by law in all jurisdictions in Humboldt County. The first vaccine lasts for one year, then three years thereafter. Cats: • FVRCP vaccine • Leukemia (FeLV) vaccine • FVRCP: This vaccine protects against the most common causes of feline upper respiratory disease as well as the feline parvovirus. While it is very effective in preventing panleukopenia, it is less effective at preventing upper respiratory disease, but can result in less severe symptoms should an animal become infected. This vaccine requires a series of doses for full protection- it is given every three to four weeks until the cat is at least four months of age. Vaccination lasts for three years after the initial series and a booster one year later. • FeLV: This vaccine, when paired with a negative FIV/FeLV test result, can effectively help limit the possibility of contracting FeLV. Kittens are the most susceptible to contracting this disease. This vaccine requires a series for full protection. We recommend that cats 12 weeks and older receive the first vaccine. An additional booster is needed in three to four weeks. After the initial series, this is an annual vaccine. Dogs: • DAPP vaccine • Leptospirosis vaccine • Bordetella (Oral) vaccine • DAPP: This vaccine protects against canine distemper, canine infectious hepatitis, parvovirus, and parainfluenza. Parainfluenza is one of the pathogens involved in the canine infectious respiratory disease complex. Parvovirus is a highly contagious gastrointestinal virus that typically causes bloody diarrhea and vomiting. Distemper and parvovirus vaccines are very effective in preventing disease. This vaccine requires a series of vaccines for full protection — it is given every three to four weeks until the dog is at least four months of age. Vaccination lasts for three years after the initial series and a booster one year later. • Leptospirosis: This vaccine protects canines 12 weeks and older against four different variants of Leptospira. This zoonotic disease is common throughout the US and is typically found in standing water and infected animal urine. For full protection, this vaccine requires a series. We recommend that canines over 12 weeks of age receive the first vaccine. An additional booster is needed in three to four weeks. After the initial series, this is an annual vaccine. • Bordetella (Oral): This vaccine protects canines from certain forms of Kennel Cough. It is given orally and needs to be boosted annually. We recommend canines over eight weeks receive this vaccine.

Testing & Microchipping... $26

• Heartworm testing: Heartworm testing is an easy way to check if your dog has heartworms—parasites that live in the heart and lungs and can cause serious illness or even death. A small sample of blood is taken from your dog and results will be available to you the same day. Testing required for heartworm prevention and recommended for dogs over 6 months old. • FeLV/FIV testing: FeLV (Feline Leukemia Virus) and FIV (Feline Immunodeficiency Virus) are contagious viruses that weaken a cat’s immune system and can lead to serious illness. A simple blood test can detect these viruses, with results available in just a few minutes. We recommend testing for: •Kittens and newly adopted cats •Outdoor cats or those exposed to unknown cats •Cats showing signs of illness Early detection helps protect your cat’s health and prevent the spread to others. Microchipping: • Microchips, small transponders about the size of a grain of rice, are injected under the skin between the shoulder blades to serve as a permanent form of identification for your pet. This simple procedure can help increase the likelihood of your pet returning home if they ever get lost or stolen. The $25 fee covers the cost of the microchip and includes lifetime registration for your pet.

Trap-Neuter-Return (TNR) Program

Trap-Neuter-Return (TNR) is a humane and effective approach to managing feral cat populations. Our program offers: • Spay/neuter and Medical Treatment: We are here to help ensure all feral cats get spayed/neutered. Check out our feral cat package for more details. See an injured cat? Please give our office a call for options. • Humane Trapping: We offer humane traps for loan and guidance on how to properly use them. Depending on location, we may have volunteers to help trap. • Fostering and Socializing Feral Kittens: We provide resources and information on fostering/socializing kittens. Depending on rescue availability, we may be able to place kittens in a local rescue through our Transfer Kitten Program. • Support: We understand managing feral cats can be stressful. We are here to provide guidance and resources as they are available to us to help our community thrive. Benefits of TNR: • By preventing breeding, TNR creates non-breeding colonies that help stabilize the population. • It eliminates behaviors associated with mating, such as yowling and spraying. • TNR is a cost-effective approach rather than capturing, euthanizing, and disposing of feral cats. Additional subsidies, when available, are provided by community donations, grants, and other funding sources. We are here to help!

Frequently Asked Questions

There are feral cats in my neighborhood. What should I do?

Give Humboldt Spay/Neuter Clinic a call—we're happy to help! You can also visit our TNR page for more information.

My animal is in heat, can she still get spayed?

Cats can still go through with their spay, whether they are in heat or not. Dogs, however, we recommend waiting 2 weeks after they are in active heat. Call the office for more info on dogs in active heat.

My female cat had kittens, and I’m overwhelmed. What are my options?

We're here to help! If you have homes lined up for the kittens once they’re weaned, we offer a great package to have the mother and kittens fixed. If you'd like to surrender the kittens to a rescue, we can refer you to one directly or possibly accommodate them through our transfer program. Please call our office to discuss your options. Whatever you choose, please do not give away unfixed kittens.

Does my dog or cat have to be fixed to use your services?

Vaccines are offered to all animals regardless if they have been fixed. At this time, our other services like exams and dentals are only available to animals that are spayed or neutered. However, if you schedule a spay/neuter appointment and place a deposit, you may access other services prior to the surgery. Please note: your deposit becomes non-refundable if you use these services before the spay/neuter appointment.

How old does my animal need to be to get fixed and receive other services?

Cats must be at least 8–10 weeks old and weigh a minimum of 2 lbs. Dogs must be at least 4 months old.

Do you have an age limit?

Yes. Dogs must be 5 years or younger for spay/neuter. For dental procedures, pets must be 8 years or younger.

Why can’t you spay or neuter brachycephalic animals like boxers, Frenchies, shih-tzus, or Persians?

Brachycephalic animals—those with audible breathing issues and/or short snouts—are more prone to airway obstruction, stress-related complications, and higher risks of aspiration during surgery. For their safety, we recommend these pets be seen by a full-service veterinary clinic. If you’re unsure whether your pet qualifies, we offer free snout checks in person or by photo.

Does your facility offer emergency services?

No. Unfortunately, we are not equipped or staffed to hospitalize critical patients or provide the radiology typically required for emergency cases.

Does your clinic offer radiology (X-rays) or other in-house diagnostics?

We are not able to perform general radiology. However, thanks to some amazing local donors, we have dental X-rays as part of our dental program and now offer in-house blood and urine analysis though our diagnostic lab.

Where can I get financial assistance?

For spay/neuter services, local voucher programs are available. *Once your appointment is scheduled, we’ll connect you with the right contact to request a voucher. We also offer in-house financial assistance. *Dental and medical services may also qualify for in-house support through various funding sources—just ask! *While funding is available.

Do you accept CARE Credit?

No, unfortunately, because we are a non-profit organization, CARE Credit business fees are too high.

Do you accept checks?

We do not accept checks as a form of payment. However, we gladly accept donations by check!
