We had a delightful doggy-themed giveaway earlier in the week, so now it's time for the kitty cat's place in the spotlight.

Unfortunately, I don't have any cat DVDs, but I do have this awesome "Big Bang Theory" Soft Kitty t-shirt and singing plush kitty cat combo! I mean, honestly, this is pretty cool.

"Big Bang Theory" fans know that the "Soft Kitty, Warm Kitty" song is the only thing that makes Sheldon feel better when he's down, and now there's a stuffed kitty that will sing it for you!

The t-shirt is a size large (and we're thinking it's for women, but we won't judge) and it looks tan in this photo but the one we have is light gray.  It's cute.

We're throwing in a novel by Shelia Roberts called "The Nine Lives of Christmas." I'm not sure what it's about, but there's a pretty orange cat on the cover.

Also, you'll get a Japanese book (translated to English) called "Crafting with Cat Hair," which -- I promise -- is not as weird and gross as it sounds once you look at the pictures inside.

Send me an email by midnight tonight to be entered in the drawing. The winner will be notified by email. Include your mailing address with your entry to make things quicker on this end.

Meow!! (Good luck!!)
