I have a question concerning the yard mulch some people use around the yards.I talked to a worker at that nasty pet store in peoria and she pointed out that the owner uses yard mulch as the substrate.I also talked to the owner himself and he said that "reptiles magazine" said its ok to use the yard mulch .I find this very hard to believe .In my opinion its just being a cheap *** and sadly the snakes will suffer as they will tell buyers of the snakes to use it also.So tell me your thoughts on this "yard mulch"
