Thanks everyone!
We so wanted and waited and checked all over for her to be a rescue....but nothing was available until we couldn't take it anymore...
So we 'rescued/adopted' her with a bit of cash from a lady who adopted her from her mom who just passed away....and then needed to rehome her due to her own bad cat allergies.
Twiggy is coming around a bit.... it's taking a few days longer than I thought - but they'll be buds soon. Never had 2 female cats before.
And now all females in the house except for me -
