Spay and Neuter

The Humane Society of Ventura County operates a Spay and Neuter Clinic for residents of Ventura County needing a low-cost option for their pets. Appointments are required and can be made by calling (805) 646-7849. If you are not helped immediately, please leave a message and we will do our best to get back to you in 48 hours. Please note that appointments for large dogs are often booked out 4 to 6 months and we only service residents in Ventura County. Please note that we no longer accept bills over $20.

While we love to help all of our furry friends with their spay/neuter surgery, we have a limited number of appointments available, and we aim to provide our services to those who are unable to afford the procedure at their full-service veterinarian.

Pricing is generously subsidized by donations, grants, and sponsorships. If you require additional financial assistance, please speak with a staff member at 805-646-6505 when scheduling an appointment. For information on our Feral Cat Program please CLICK HERE.

Please note that we require a $10 deposit to schedule a cat surgery appointment and a $25 deposit to schedule a dog surgery appointment.  Deposits will be forfeited for any appointments not canceled within 24 hours prior to the appointment. 

• Male cat: $50
• Female cat: $75

• Dogs 5-25 lbs: $100
• Dogs 25-50 lbs: $125

  • Altered animals are better companions. Because they are less likely to roam in search of a mate and to participate in aggressive behavior, they can live longer, healthier lives.
  • Neutered cats are less likely to spray and mark their territory.
  • Spaying a female dog or cat removes its heat cycle, which eliminates the constant crying and nervous behavior they display for a week to two weeks, as often as two to three times a year.
  • Spayed and neutered pets are less likely to bite than unaltered animals.
  • Even if you are able to find homes for all of your animal’s offspring, allowing your pet to have babies contributes to the pet overpopulation problem by reducing the number of homes available for animals awaiting adoption in shelters.
  • While the Humane Society tries its best to find homes for all animals under its care, the sad fact is that there are not enough homes to go around.
  • Altering your pet will not lead to it getting fat. Animals gain weight because they are fed too much and are given too little exercise. Removing the reproductive system eliminates organs that are subject to infections, tumors and cancers.
  • Your pet should not be used to teach your children the “miracle of birth,” unless you are also prepared to teach them the “reality of death.” Unwanted animals are killed by the thousands each day throughout the United States, making it a tough lesson to learn, especially for the animals.
