"dsclp" is correct! This is fantastic news! Feral Kitty is wanting to interact with you. That is so awesome and amazing! I'm so excited for you both! Talk back to her quietly, calmly, and sweetly when she meows at you. Maybe settle on a name? That way Feral Kitty can get used to hearing it and connect it to herself- and more bonding can happen!
YAY!!!
YAY!!!
