I love coco mulch, I personally think its heaven sent. I avoid the whole situation you described by usually using a feeding bin for mealtime. I just have paper towels for that.
I would hate for you to blast coco mulch just because of this one incident.Its greats stuff, IMHO. There are lots of us who like it, and if you feed outside of their enclousre you won't have this issue, although I recognize this may not be something you do![]()
