Hmmmmmm Thanks for the info.
Cats instinctively use the litter box. When you get your next cat, just show him/her where the box is, make sure you get a good litter like Fresh Step and you'll be all set. A cat peeing else where just means there are either health problems involved or behavioral issues related or caused by external factors such as stress from kids, a new animal, moving, another cat roaming around, or you or anyone in the house experiencing hormonal changes , for instance, you getting pregnant.
How to get them to use the litter box only/why they would go else where in the house.
I don't think I understand your point or question?
