I keep my vertical blinds closed and the horizontal ones open. Yes, it's inconvenient because my apartment is level with the parking lot and people can look in if they want.I think I need to upgrade my blinds to wood slats. My cats keep breaking the plastic ones.
The alternative is ruined blinds and a hefty penalty to replace them. I don't get to choose the paint or blinds for where I live, so I just have to keep things as "cat proofed" as possible.
If you get wood blinds, just make sure the cat doesn't take one look and think, "Oh, new scratching post! My human is so good to me!"
Mundane plans... my soap opera is on in 5 hours.
