Well everyone, Leslie took Fawnie home for a "trial" run to see how it works out. My heart aches because she IS such a wonderful cat and I just have this gut feeling that she and Min will be best pals, after some time.
Leslie, like everyone has said, TAKE IT SLOW. Don't expect anything to happen overnight. Let your mother bring Fawnie in the house. When you put her in her room, keep the door closed at first, before you put up the baby gates. This way they'll get each other's scent. After about a week, THEN put the gates up. You don't want to freak Fawnie out with Graham and Kersey.
Keep me posted. This will work out if you just give it time. This is the best way to find out.
Give her kisses and head bumpies from me and the gang.
