Our Mission Statement

To significantly reduce the overpopulation problems and high euthanasia rates of felines and canines by providing low cost spaying and neutering programs.  To provide education programs focusing on the necessity of spaying and neutering as a means of controlling domesticated and feral populations.  To provide assistance to unowned, injured animals.  “It is our hope that by addressing the reasons for pet overpopulation and abandonment, we can begin to alleviate the problem through spay/neuter campaigns and funds designated to medically treat and find homes for homeless, injured pets.”

"...I dropped Sammy off at 8AM on Thursday and was greeted by friendly staff who once again told me what to expect.  I had a good feeling that these people would take good care of Sammy.  I was instructed to return after 130 PM to pick up Sammy.  i returned later in the afternoon and was given detailed instructions for post-procedure care for Sammy and told to call if I had any further questions or concerns.  The procedure went perfectly and Sammy was a bit groggy when I picked her up and was her usual self within three days.

I can't say enough about how professional, knowledgeable and friendly the staff here are.  They really make sure you are totally informed and feel comfortable.  They also told me that I can bring Sammy back, with an appointment, to receive vaccine shots.  I will be back for sure!" -Robert M.

"This place is great. We took our 6 month puppy here to be spayed. It was affordable, convenient and things were done the right way. Dropped our puppy off at 8am, and picked her up at 1pm. Very nice and informative at the front desk, they offer cones for $15 to keep your animal from disturbing the area. They also instructed us how to care for our pup after the proceudre.The incision was very small, maybe about 1.5 inches or so. This helps speed up the healing process. Would recommend this place to anyone who needs their animal spayed or neutered."

"Found out about this place after I was given a quote of $400+ from my vet for a spay. It was too much for me to give out of my pocket so I searched for a better option. This place charged me $60 for the spay, I also added a micro chip and a rabies shot and paid a total of $110. I went to drop my puppy off at 8:30, and was very stressed and anxious. The ladies at the front desk were very nice and friendly, the answered all my questions and made me feel like she is in good hands. I was told that pick up time is 1pm, but I went at 12 and she was ready to come home! Surgery went well, the incision was small and stitching was great. Not even three days later and my puppy was full of energy and feeling great. Its been a week now and the wound is almost fully healed and barely noticeable. I want to thank this place for doing such a great job, from front desk service to vet work, it was all a great experience at such a reasonable price! I highly recommend taking your furry babies there, they will be in good hands!" -Gaby B. (Yelp)


Q: When should I spay/neuter my pet?

A: The best time to spay/neuter your pet is at 4 months to prevent unwanted litters. Spay and neuter EARLY!

Q: Isn't it better to let my female have one litter before I spay her?

A: No, the best time to spay a female is before her first heat.  This also reduces risk of breast cancer later in life.

Q: Will my pet still spray after they are fixed?

A: Fixing your pet will help reduce the need to spray and mark their territory.

Q: Does my animal exhibit temper issues because they are not fixed?

A: Unsterilized animals often exhibit more behavior and temperament problems than do those who have been spayed or neutered.

Q: What if I just let my female go through her heat cycles?

A: Spaying a dog or cat eliminates her heat cycle.  Estrus lasts an average of six to 12 days, often twice a year, in dogs and an average of six to seven days, three or more times a year, in cats.  Females in heat can cry incessantly, show nervous behavior, and attract males.
