Yowza, Mantenna! Glad that you still love cats.... and that Dad's okay! That must have been quite the harrowing expeience...
Here's my suggestions (bad, though they may be)-
Phoebe and Ursula
Mini and Maxi
Lois and Trixie
Eva and Zsa Zsa
Although, I think Madeline and Chloe are cute too! (Heck, what do I know-- my 2 female cats are Boommer and Simon...LOL)
