I had a small pile of very kinky yarn and plopped it on Murderface's head (that's what you get when you nap next to me on the couch, buddy). It looked like cool dreadlocks so I decided to make a cat wig. I knit a basic hat base from Cats in Hats, cut the kinky yarn into 6 in - 8 in strands and then used a crochet hook to loop the yarn along the garter ridges of the hat base.
I'll get a better picture in the future. She was napping and kind of... unimpressed with being disturbed for this nonsense. It was a fast and fun project to whip up in under an hour.
