The Pet Overpopulation Fund was established by Colorado statute. The Fund exists to educate the public about the importance of controlling pet overpopulation and to work with animal shelters, veterinarians and communities to curb pet overpopulation in Colorado, ultimately ending the need for animal euthanasia due to unwanted pet births. The fund subsidizes sterilization for Colorado’s pets by providing grants that support collaborative efforts between veterinarians and animal care and control agencies.
