Our kitty Xia goes to grandma and granddad for a couple of sleepovers. While we are away skiing. We are sure she behaves well. Not so so sure about grandmas cat, named "Grisli" --> derives from french "little grey one", who has outgrown his name and is a hug dominant cat. But Grandma (my mum) separates them, so everyone has plenty of own space. Xia even brought a mouse last night, probably a hospitality gift, but I catched it and released it to enjoy freedom again.
Have a nice sky holidays
