“.. when my mother came over to visit, he was all over her and ignored me”.
I love that story, HerrBlucher! Almost like the kitty knew she had a challenge. You will lovz me, Grammy and luvz me now”. (now why do I think that your Mom really did start loving your kitty?!)
My children and I lived for a few months with my parents while we were looking for a house in the area. My father “hates” cats, but my cat loved him. He would sit talking about how foul cats were, while she stood on his knee, being petted and sticking her claws into his skin. :)
