When Melly first arrived, I set up her isolation zone in the bedroom.
Then it occurred to me that Scarlett would not be pleased to be separated from me at night, and so Melly was relocated to the bathroom. I periodically swapped the cats (Scarlett in the loo, Melly out) to let Melly expend some of her crazy kitten energy. Of which she had (and still has) lots.
Happy gotcha day, my goofy girl! I'm so happy you're mine.
