The main purpose of the Contracting Accountability and Transparency Act, also known as the CAT Act, is to enhance transparency and accountability in the contracting processes of public housing agencies. This legislation aims to ensure that the public has access to important information regarding contracts that these agencies enter into, thereby promoting responsible governance and oversight. The key provisions of the CAT Act require the Secretary of Housing and Urban Development to mandate that all public housing agencies disclose specific details about their contracts on their websites.
