I've had trouble with the cats wanting to mark anything and everything in my house. I found this on clearance and thought to just give it a try. Because I wasn't sure that it would really keep the mattress dry, I placed a fabric shower curtain atop of the protector. When the day came and the cat had Marked his territory, I found that the protector had absorbed the bad and my mattress was clean and dry.  I am sold on this product.

Pros: easy clean and holds its shape.
