I’m currently drying the foam in the sun after dousing them with water & detergent, pet deodorizer and Febreze. I’m washing the covers as we speak, on gentle. If this doesn’t work, what would you try?

Thanks…it’s faux leather, by the way.
Pee, definitely. We had puddles before we figured out the cats wouldn’t use the litter box if it was near the food dish.

They haven’t done it in a long time but with the warm weather the smell is really coming out, and not in a nice way.
