I've created a santa outfit for my cute little cat, and he just runs around in it like no big deal :D but it does eventually come off.
The christmas sweater is a modification from the candy corn sweater from DIY Maven. The hat I did completely on my own, and unfortunately do not have a pattern for - I just winged it :D The "chin strap" is the beard as well.
And yes there were definitely some booties :)

Even our family cat, Butternut, got to wear it, but he doesn't really look that happy about it...
