OUCH!

So, I'm still in my pajamas enjoying one last cup of coffee before getting ready for work. One of the kittens is perched on a piece of furniture and I walk by. Suddenly I feel pain shooting up my back as the kitten decided I would make a great tree to climb. Several scratches later, she sits on my shoulder purring in my ear. How could I stay mad at her? (Still, I wouldn't want her to do this again. Lol)
