Why do my cats pee outside the litter box and how to get them to stop?

[kkmarcs]

Hi there,

I have been having an issue with my cats for a while now. Their litter boxes are in a room that has hardly anything else in it, I just use it as an office from time to time, and they always pee on the floor. It's almost always wet directly outside the boxes and the whole room smells like cat pee. I have used so many products to try and get the smell out. Thankfully its just hardwood not carpet, but it still stains! And it really smells. I've tried everything I can think of. My cats get along great, they have tons of space, clean litter always, and are hardly ever alone! Nothing has changed recently, like I said it's been going on for a long time, so I have no idea what's causing it. They are also in good health, they're 1 and 2 years old.

I've had cats my whole life and have never experienced this, does anyone know what the problem could be? Or have suggestions on how to stop this??
