Wow!!! I thought that my Alani & Blaze were little terrors. I used to have those same type of metal blinds but Pearl tore them up when she was a kitten so I now have the roll up shades. They aren't kitten/cat proof but they're a lot better than the metal blinds. I'm sure that if I let Alani & Blaze into the bedrooms that they'd also tear up my shades too. Good luck with your little black tornados.
