My Cat Thinks Size Doesn't Matter

I have this little cotton pillow that's filled with dried corn. When I heat it in the microwave, it becomes the perfect heating pad for sore muscles. My shoulder was killing me the other day and I'd been using the magic pillow for most of the morning. I returned from refilling my coffee, only to find Cosmo's hijacked the pillow! And why wouldn't he? It's the perfect size for his head, and one of his favorite hobbies is stealing my pillows -- I guess size really doesn't matter.
