If you are very houseproud and a clean freak, I'm not sure that having a pet like a cat (or a dog) would really suit you. I'm looking round my house at the drifts of soft grey fluff that my 2 short haired indoor cats have produced - I'm picking up handfuls every day at the mo but they are STILL shedding their undercoats! There's also fluff & hairs on my bed, as Girlcat loves sleeping on it during the day, and it sticks to clothes like nobody's business.
As slightly shy adults, mine are very good at (mostly) just using the posts on the cat tree to scratch, but I still have gouges in the wallpaper & scrapes on the windowsill where Boycat, who is thick & clumsy, has made a mess of jumping on or off the windowsill.
My windows aren't looking terribly attractive at present. It being a warm summer so far, I like to have windows open for a breeze which you can't do with indoor cats or they will inevitably get out. So I have Flatcats screens on the windows in the living room & my bedroom so I can get the breeze & they can't get out.
If you have ornaments, better get them in a cabinet of some form. If there's a shelf then the majority of cats will want to explore & likely knock down something breakable.
All that said, I wouldn't be without my furballs now. But I'm not at all house proud & am quite happy to reorganise my house round them.
