Very disappointed.  I bought the pad last year and used it for my dogs just once.  I put it away in the original box in a plastic tote.  Two days ago I got it out and it had some greenish spots and an awful moldy smell.  I cleaned it hoping that spots and odor would go away.  Today, I threw it away.  I don’t remember how I paid for it at the pet store, but it wasn’t cheap.  What a waste of my money.
