You guys are too funny. Fortunately the mini-blind wars haven't hit this part of Chicago yet. Then again, we don't have them on any windows that are conducive to cat-sitting, so they don't come in close contact, which may be the solution. Keep the cats and the mini-blinds separated and no wars. But then again, that would be segregation and we can't have that. They will have to learn to co-mingle and live together in peace, like the rest of the world.
