I suspect you meant 10pm to 7am...but I agree with the other posters...I would provide a litter box for them overnight. If you don't like having a box out and you have no space, then why not scoop the box first thing in the morning once the cats go back outside and then tuck it away at the bottom of a closet or some other out-of-the-way place. That way, the box is only out overnight, and since you're sleeping anyway, you won't notice it.
Dogs have owners. Cats have staff.
