In my fort

I had to stay home from work today to take care of a sick kid, so I grabbed the hardware I needed from the office and set it up at home. I've got three laptops on three sides of a square table, with the power cords trailing off the fourth edge to a power strip. There's also a couple external hard drives and mice in the mix. This worked fine all day, until about 4:30, when my cat slowly saunters across all three keyboards, and noses my hand. I pull him into my lap, but as soon as I stop paying attention to him, he's back on the table. Finally, he lies down to rest.
I hope he's not contaminating the chain of custody form he's lying on.
