What Do You Get When You Mix Cats And Your Long Boxes?

Here are the culprits:

They look so peaceful, don't they?How could those sweet napping kitties ever be anything other than perfect little angels?Well...we introduce cardboard into the equation.My cats love cardboard.

This damage was on both of the exposed long boxes.It only took a matter of months to get like this.

Do you see all of those little scraps of cardboard in the box without the cover?I'm still finding those things 3 months later.

They actually clawed their way all the way through the box.

To stop this from going on I had to duct tape the tops of my long boxes.

I did that to both of the exposed ones.For some reason the cats won't sit on the duct tape.To be honest, I don't really care why.All I know is that my boxes aren't being ripped to shreds anymore.
