You're weird. There's no other way to say it, dear.
I love that you're a lapcat, and I adore the way you roll around, loll, squirm and wriggle, paws everywhere when you're getting scritches. But seriously... the ears were back, the eyes were slitted and fangs were showing. You were even lashing your tail. It looked for all the world like you were planning to eat my face. Meanwhile you were purring up a storm.
Please sort out the kitty body language thing, honey. Otherwise you'll confuse anyone that doesn't know you as well as I do. That 'demonic black cat' look was freaky!
