Colorado just passed a law that could change the lives of lab animals. Dogs and cats used in health research can now be offered for adoption before being euthanized. For decades, these animals were often put down after experiments. Now, some may get a real second chance.
The law, SB25‑085, applies to any facility doing health-related research. Surviving dogs and cats must first be offered to shelters or rescues. Facilities can also try internal adoption programs.

Annual reports will show how many animals were used, transferred, or adopted. Facilities acting in good faith are protected from legal liability.
This is more than a policy change. It is a shift in how we value animals. Research animals are living beings. They are not disposable. By offering adoption first, Colorado acknowledges their lives matter. Shelters may see more dogs and cats. But the hope is clear: lab animals can leave cages for forever homes.
Transparency is a key part of the law. Facilities must report to the Colorado Department of Public Health and Environment. This creates accountability. People can see how many animals are truly given a second chance. It also sets a standard other states could follow.
The law has its limits. Euthanasia is still allowed if necessary for health or safety reasons. Shelters may face challenges with more animals. Adoption depends on public willingness. Yet, advocates are optimistic. Officials and animal welfare groups call it a landmark victory. Governor Jared Polis praised it as a step toward compassion in research.
For the first time, surviving lab dogs and cats in Colorado may leave sterile cages behind. They could find warm homes, soft beds, and families that love them. This law does not end animal testing, but it gives hope to those who survive it.
Colorado has shown that science and empathy can coexist. Lab animals may now live again, not just survive. Their second chance is real. And for many, it could be the life they deserve.
