The United Kingdom would take a major step forward in 1986 when it replaced the Cruelty to Animals Act of 1887 with the Animals (Scientific Procedures) Act. Distinguishing itself from the original Act, ASPA was implemented to specifically regulate the use of animals for research purposes. Under the direction of the Home Office, ASPA clearly defined various issues that had previously been ambiguous such as protected animals, husbandry and care protocols, and judgements for licencing of use. Similar to the Animal Welfare Act of the US, the passing of ASPA was a critical progression towards modern legislation, advancing on scientific findings and public opinions of the previous century.
