"Nursing" the neck - LOL! My Trixie did that once (only once, thank goodness) when she was just a few months old. I woke up with a "necklace" of tiny love marks! Fortunatley, it happened on a Friday night - they had faded by the time I went back to work on Monday. However, I got my hair cut Saturday morning. I finally explained the marks (which were quite obvious) to the gal cutting my hair. Thank goodness, she's a cat owner too and got a good laugh out of explanation. She had noticed them right away but was too polite to mention anything!

I had to sleep for a while with the covers pulled up tight around my neck, but Trixie finally gave up on the attempt. She still nurses my hand occasionally though.
