Need name theme for pregnant cat

I foster through my local humane society and today I picked up a pregnant mama cat who doesn't yet have a name! She is a tortoiseshell. I was wondering if you wonderful nerds could throw out some themes I can use for her and her kittens. I have no idea how many she'll have. Additionally, the shelter recommends "marketable" names, so ones from TV shows or popular franchises can help get people interested in adopting her and her babies, but it's not a must. TIA!
