So long story short - I had extremely moldy KMS hay recently, like half of the box at least. I tossed out the hay, had terrible customer service from them and decided to buy from Small pet select. Everything was great, hay was much better, smelled great, until last night when I smelled the mold smell again! I sorted through the box separately by smell (yes really) and it took me a while, but I found it. So now I guess I will contact them? Has anyone else had a problem and know what they do for it? I just want to know do I need to throw all of the hay out? The last box I did because it was so much of it, but I hate to throw away another whole box (but will if I have to obviously). I've never had mold in any of my hay in the last 5 years so I'm frustrated that this keeps happening-hay isn't cheap!
