I sure loved trying to figure this all out on my own xD Sure it was a pain, but it actually did come through at the end, once I figured out how to get the basic reskins to work. I thought all had been for naught for a while there, before I realized...I put the treepath in the wrong file. So I tried it again, and...
This reskin goes over the basic cougar/lion skin, like what you see in Barrens or Mulgore. I put it on a basic treepath so I'd be able to find the skin in-gam easier xD
Now all I need to do is figure out how to put this cougar model into the tauren druid file so I don't get that dumb horned cat, edit this up a tad so it looks more clean, and I'll have this for a cat formOf course, easier said than done...I'll figure it out somehow.
