Don't Let it Loose

Releasing a pet to the wild is never the right thing

For the health of your pet, and the safety of our native wildlife, it’s never OK to release animals. Most pets released to the wild do not survive, and many suffer before they die. Pets are usually unable to find food or shelter in the wild and they are often an easy meal for another creature. If it does survive, your pet becomes an invasive species that native wildlife may not have the defenses to compete against. Invasive species cause harm to the environment and the economy.
