WOW. Thanks for this. I bought xylitol for the first time last month, but it isn't a sweetness I can taste. I hadn't planned on buying it again. I did notice a problem with the dog one night (seizure) and tried to figure out what foodstuff might have caused it (he is on a limited 3 item? menu) but it might have been something with the xylitol... sprinkled on the floor and he licked it up? SIGH. No more of that in the house.
