I have 5 and have 3 covered boxes. One is upstairs in my bathroom, and the other two are under the stairs (I live in a loft apartment), separated by a bookshelf. My boxes are covered because one of my boys is sometimes in such a hurry to pee, he doesn't sit. So, he ruined one wood cabinet and the wall of my bathroom was starting to get messed up with cat urine. I had no choice but to go with the covered boxes. The boxes get cleaned daily, and I use Swheat Scoop for multiple cats. If I had more room, I'd add more boxes, but luckily they don't seem to mind sharing.
