Hi a couple of my cats sometimes wee on our sofa or bed when they are in season,have your cats been done?also when you clean the area with simple solution make sure you soak it really well so it gets right in!and let cushions dry completly before putting on.i have 5 adult cats in at the moment and 2 litter trays,
