You'll like this one ernyoka, even though it isn't exactly what you're looking for. I remember this one because originally they featured actual flatbed scanner scans of pet cats- which was a great reference source for hair- but apparently too many people thought that was being "cruel" to cats, so they now only feature portraits- but haven't looked at them all. (Could be some Hentai Cat stuff in there!)
