I was wondering if any other cats out there do this: Mia likes to literally knock skulls with me! I've seen and heard of head-butting because they want to be scratched and to show affection, but she likes it even more when I lower my head to her and she can really smack her head against my forehead. She does it so hard that sometimes it actually hurts! And she's a teeny little girl! I know it's all out of love, but still. It's kinda weird, am I right?
