I know this has been on the forum. I can't remember it or find it. What is it that we dust the ff with before feeding? Could you provide the name of the product and where you've gotten it and approximate cost? I totally forgot to get this item, and my tinks get here today. Can I buy it in the pet store instead of ordering? If not, will a week(waiting for it in shipping)cause any problems to my tinks? Probably not, but I'm just paranoid.
