Normally when I buy this probiotic drink mix from Pets at Home store it always dissolves easily, and is a beautiful deep green colour. Last month I bought one container from Pets Connection on Amazon. The product didn't dissolve like normally. Had to stir and stir, and after it did mix in, the water turned out to be a pale green colour. Should I throw the rest in the bin? Demand for a refund? Demand for an exchange? Let my bunny carry on drinking it?
