I've got an old white macbook and a newish retina macbook pro. Typically these live on my desk stacked on top of each other, with keyboard/monitomouse plugged in. My cat likes to sit on top of them because they are warm. She also likes to chew on nearby cables. This is a problem. So, here's this Thing to stand them vertically! Kitty came by looking for her warm spot, but didn't stay long. My desk is now clearer, but also more lonely. ... success?
