Obsolete version. Even though this file is much bigger than the recent version, it does NOT contain more footsteps (actually, it contains less). It's just less optimised.

NOTE: Now contained in the main installer; no longer any need to download this file separately. Makes the cats' footsteps in Qasiermo's Pets of Skyrim softer, less bassy, and more muffled. Requires Pets of Skyrim
