I would ask if they have other cats/animals in the home, how many litterboxes they have (# cats + 1 extra), how often they are cleaning the litterbox, if they switched litter types recently, if the litter is scented or unscented, if the cat is fixed, where the litterboxes are in the home and if they are covered or uncovered (many cats like to be able to see around them while peeing so covered litterboxes don't work, if their litter box is uncovered I would suggest adding a covered one as well), if the owner has started changing things in the house to prepare for their baby that could also lead to stress and peeing outside of the litterbox. I would also suggest if they haven't tried it already, there are some citrus sprays that you can spray where they've been urinating and that could deter it as well.
