Oh Topcat3, I wasn't going to post this until I read your response, he he.

My home had vertical blinds when I bought it, but we hated them. You can't close out the sun and still see, as the top of the window is "open" unless you draw them allt he way across. So switched to shades. Those I can pull down part way, 3/4, and still see out.

When the kitties get antsy, they chew on the shades, so I have holes in the edges on one or two. Thank goodness those are in the rooms where I put the cheap ones. I have room darkening in my bedroom and fancier shades in the living room, and those haven't been touched in 4 years.

I do NOT have curtains, just valances at the top. This was fine until . . . last evening. I brought in one of the female TNR cats, thinking I may keep her. She FLEW from the floor to the valance in a second! The whole thing came down on her, which didn't go over to well with either her or Dad. The nails pulled right out of the wall. So now we all know what my Dad will be working on today.

We still have curtains up, at Dad's house. When we go up there and stay a week the cats come with us. And those curtains are in shreds, I keep trying to find time to remove them. Maybe next trip.

Blinds inside the windows, yeah, I think those may be kitty proof. Good luck!!!
