You should be able to search online and find tips on how to skin furbearers. I'm not sure what's out there on making rugs, but personally, I would seek a professional taxidermist to do the rug, especially if this is your first attempt at anything like this. Your going to want it to come out nice and it would be disappointing if you have problems with skinning, tanning, or other steps in the process. After bringing the cat to a reputable taxidermist, you may want to practice skinning, tanning, etc. on other species in order to develop the skills necessary to do future rugs on your own. Just my 2 cents on what I would do.
