I've found that DeviantArt is a pretty good place to look. ^^
Goldchocobo has a very nice feline overhaul: https://www.deviantart.com/aquachocobo/art/New-Fur-is-Here-364995756
Tearless also has a lovely feline overhaul: https://feral-heart.com/smf/index.php?topic=57194.0
NorthernRed has a pretty diverse selection of textures to offer. They're not free, but all of them very reasonably priced! https://www.deviantart.com/northernred/gallery/51602948/FrealHeart-TEXTURE-for-sale
This one is free, though: https://www.deviantart.com/northernred/art/Free-thick-and-puffy-feline-texture-511328847
