UPDATED - 2.0

Gives Khajiit tails to all playable, non-Argonian races. UPDATE - There is also an optional .esp that will give even the Argonians Khajiit tails. If you would prefer tails you can craft, equip and enchant, I have another mod for that: http://skyrim.nexusmods.com/downloads/file.php?id=13995

This version of the mod (2.0) does NOT modify races. It replaces the default skeleton with renamed copies of the skeletons used for Khajiits and Argonians. As far as I have been able to tell, this does not cause any issues. If you use another mod that modifies beast skeletons, you might need to copy and rename those to replace the skeletons I've provided to prevent conflicts.

The .esp itself is very small because it only edits the NakedTailKhajiit armor add on and the SkinNaked armor. As such, conflicts with other mods should be unlikely, but admittedly not impossible.

Don't want this mod to apply to so many races? This is easy to change with the CK. Open the NakedTailKhajiit armor add on and change which "additional races" are available (if they're highlighted in blue, they will have the Khajiit tail).

To install:

Unzip and merge with the Skyrim data folder.

Delete or deselect khajiittails.esp, then delete, rename, or overwrite the skeleton files. They can be found in the skyrim folder under the following paths:
