You may have heard of kitten mittons... I present you Kat Hats!
I found this simplicity pattern for pet clothes and upon putting one together for my dog, I had to make them for my cats as well. Aurora's (in the pink) is a little big for her, so I have to make some minor adjustments. I also cheated and made them out of felt, because I figured they probably wouldn't really wear them that often.
