I think we've got it all wrong! Those brown square things are the Wrath of God. That's how the Almighty dispatches the kittens. Just imagine, every time someone whacks off, some of those brown things chase down a kitten and... well...
I'm surprised they've never been caught on film before now; you'd think we'd be up to our ears in the damn things. What I'd like to know is: if God punishes kittens for us spilling our seed on the ground, what onanistic member of the animal kingdom accounts for human mortality?
