Rating/Warnings: Rated PG/T for an "awkward boner". (Thank you, Lisa.)
Word Count: 5,370.
Summary: The wildcard prompt words were "waffles, kitten, pillow, outlast, tuxedo". I was incapable of ignoring a prompt with "kitten" in it. I make no apologies for the title (seriously, there are so many fics already called "Soft Kitty" and variations, one more can't hurt).
Author's rambling: Okay, so I got this one as a pinch hit and then the original writer ended up posting after all, but I was already 2,000 words in. A quick check with the mods confirmed that I should finish it anyway, because why not, and thus I proceeded to give the entire Sheldon/Penny fandom diabetes. Muahahaha. Thanks to Lisa for the beta!
