Were there cats living in the house before you moved in? Maybe they smell the other cats urine and they are trying to mark their territory? Are cats in the neighborhood urinating near your house? Maybe the cats smell that. We had neighborhood cats urinating on our door and our cat smelled it and we put some stuff by the door to keep the cats away and that helped. Also, the Feliway infuser might help. It helped our cats adjust to a new house.
