Her name was DarkWing. Which is a pretty stupid thing to call anything other than a duck, so we promptly changed it. And thus, she became Unnamed Kitty. (Just for a couple days. Now she goes by Penny.)
She's Penny because of Sheldon on Big Bang Theory. You see, when The Professor was even littler than he is now, the lullaby we sang to lull baby to sleep was "Soft Kitty," albeit with one slight adjustment:
Soft kitty, warm kitty,Therefore, it only made sense for our new cat also to have a connection with Sheldon. And what better way than to call to her with a simple <knock knock knock> "Penny"?
Little ball of fur.
Happy kitty, sleepy kitty,
She was fantastic with our son from the get-go, and she and our dog Sonya peacefully coexist (with the peace occasionally broken by a bark). She and Schrödinger, however, are like two peas in a pod—very spastic peas who wrestle and play in water and chase each other all over the pod that is our house. He shreds cardboard; she gnaws on actual boards. And wicker. (And plastic.)
Penny may not be the lap cat her predecessor was, but she's a perfect fit for us.
