We are a non-profit mobile spay & neuter clinic serving rural Colorado.

“We’re on the cutting edge of reducing unplanned litters.”

Unplanned litters of dogs and cats are a significant source of animals entering the shelter system, and there are not enough homes for these animals in our state. Rural communities throughout Colorado are in greatest need of our services.

What We Do

Every month we hold a 4-day clinic in an underserved Colorado community.

Our mobile surgical unit enables us to work in the heart of the highest-need communities in rural Colorado. We collaborate with local nonprofits, governmental agencies, veterinarians, partners and sponsors to provide spay/neuter surgery, vaccinations, microchips and education services to these underserved communities.

Our Results

Thanks to our sponsors, partners, hardworking staff and volunteers, and those who use our services, we are making an impact:

11,536 animals sterilized in 21 Colorado towns since June 2019

It’s simple math

Why the Need?

Consider the consequences of unaltered cats and dogs:

  • A female dog can have up to 3 litters in a year with an average litter size of seven puppies. That means 1 female and her puppies can create 67,000 puppies in 6 years.
  • If a female cat has 2 litters in a year with an average litter size of 8 surviving kittens, that 1 female and her kittens can create 66,000 kittens in 6 years. Cats can begin reproducing as young as 16-weeks of age!

These unplanned litters of dogs and cats are a significant source of animals entering the shelter system, and there are just not enough homes for all the dogs and cats currently in our country. That’s why spay and neuter — or sterilization services — become so important. Allowing your pet to have “just one litter” contributes to the problem.
