Hi Rochelle,
I've gotten 8 samples of faux fur from Van Dykes Taxidermy:
http://www.vandykestaxidermy.com/product/01321966/ I haven't used it yet, so I can't really say what it's like. If you're going to heat it or anything, you might want to test a bit first, as I don't know how they'll react.
An alternative to faux fur is real vintage fur, from an old coat (you can look for one at Goodwill and such), unless you really just don't want to use real fur.
