New kitty in the house..Queen Gracie is NOT happy!!..?

Wow, you sound just like me! Very sensitive to our cats' psycology and behaviors. Anyway, as much as you may worry about Gracie feeling 'neglected' or jealous, it's really up to her to accept Midnight. Don't forget, YOU are the one in charge not her. I know you love her, but I think she'll get used to him very soon. Keep loving her, and when you aren't around they'll probably bond. After all she's a cat and he is too,they speak the same language. As affectionate as he sounds to be, he'll win her trust and love sooner or later. Good luck.
