03/09/19 UPDATE! File now includes both baby cows (edit compliments of CHAOS) and adult cows! I've also updated the file to be a ZIP instead of a rar for easier extraction. 

To Install:
1. OPTIONAL (but suggested just incase): Backup your Brown Cow.xnb and White Cow.xnb files located at Steam\steamapps\common\Stardew Valley\Content\Animals
2. Download and extract contents from the zip.
3. Put the new .xnb files where your old ones were (at the location above). Make sure to REPLACE the files or your game won't know what to use and won't start.
4. Done! Launch the game and enjoy adorably fat moo-moos~!
