Trap-Neuter-Return (TNR) is now the official method to control community cats in the country and all municipalities must work in order to properly implement it. In August 2017, after almost a decade waiting in Congress, Law 21.020 on Responsible Pet Ownership* was approved and passed in Chile. This law went through several processes and mutations. It was initially made for the control of potentially dangerous dogs. Over the years new issues were included to the text, most of them related to responsible pet ownership. The final law introduced several items such as a national identification and registration plan, the promotion of neutering as a tool for population control and the prohibition of “euthanasia” in healthy animals (culling) and as a measure of population control.
