Well there was a childrens book I had long ago about a cat that loved to chase his tail and the name of the book was Johnny-go-round. So of course we had a kitty and named him Johnny Go Round. He was so loved for many years until my daughter had to let the vet school put him down due to an inoperable brain tumor. We used to sing him silly songs like "Johnny go round and round and around Johnny Go Round likes sugar" cause he would stand on his hind legs and give you a hug and face pats. You could call her Sally Go Round? If she's half as loving you've got a real treasure.
We also got a very tiny kitten once from my son in law's daughter bringing it home and her mom wouldn't let her keep it, and the little thing had an upper respiratory infection and was so snotty she literally was blowing snot bubbles. So her name was "Bubbles". She did get over the infection but the name stuck :). Or you could go with when you got her and name her April. Also had a kitten I named Peekachu, cause every night she'd get in bed, go under the covers then turn around and stick her head back out to peek at you. There's so many choices I'm sure you'll find a name that just suits her! Cograts on your new baby.
