Grumpy Cat Hard Kitty Song Baby TeeThe claws come out on this hilarious Grumpy Cat baby tee featuring the cantankerous kitty's own theme song, a funny takeoff on the Soft Kitty song from the TV sitcom The Big Bang Theory! The Grumpy Cat Hard Kitty Song Baby Tee is a black, fitted female shirt with a soft feel and a junior fit. The front features Grumpy Cat in a "police lineup" photo in front of a height chart, with the words "Hard kitty, cold kitty, knotted ball of fur; angry kitty, cranky kitty, grr grr grr." - Grumpy Cat Hard Kitty Song Baby T-Shirt
