This morning I laid out my clothes on my bed before brushing my teeth. I then turned around to find my cat rubbing her face in the arm pit of the shirt, purring loudly and then lying down on the shirt, while still rubbing her face in the arm pit. She has never rubbed her face on anything like that before, so I just let her have the shirt. Now, evening, she is lying on the shirt, curled into a ball and happily sleeping. I think I can no longer call that shirt mine.....
