One of my all-time most popular patterns, the little kitty cat hat is an adorable basic knit with cute ears on top and a little kitty face. You can get this pattern right here on Ravelry in a super easy to print PDF that includes instructions for all 4 sizes or you can view it in one size only (no pdf) at littleredwindow.com/knitting-patterns!

This pattern now contains instructions to make a Halloween Black Cat Hat with one layer garter stitch ears! Add a black shirt and your costume is complete!
