You can connect 2 ex-pens together & make a large space for them to stay safely in. One side toward the back (not in the front bc they're going to step all over it when you come home), place their pee pads. The other side, their bed & one side, their water dishes. I've read some people line the bottom w/linoleum for easy cleaning, esp if it's placed over carpet.
I have this kind in gold but it's the same brand:
