Somebody asked me that question yesterday and was surprised when I said no, since most cat care guides/experts recommend it.
Normally we have a jumbo litter box upstairs for a healthy adult cat, because I've always figured that they need the exercise that climbing the stairs gives them. We've only had an additional litter box downstairs when we've had a kitten, elderly, or ill cat, or temporarily when work was being done on the house (replacement windows or a new roof) that might frighten the cat.
Both our last cat and our current one only use(d) one box as healthy adults, so the second box was put away.
How about you?
