Pussington last night, as doing this way more than usual. She LOVES to rub the side of her face, specifically right along her teeth onto anything! She was rubbing up and down my laptop last night. If she is sitting down and you point to her face, and leave a single finger pointing at her, she will start rubbing her teeth / side of mouth along it. Is this normal? Should I be concerned? Does anyone else's cat do this?
