As this is PET talk, I think it is worth noting: Xylitol is highly toxic to dogs. Not sure re cats, other animals. So if you keep this in your home, use in in foods, keep it away from your dogs.

Stevia, I know is ok for pets -- in moderate amounts of course. Should they happen to get into the box full, I guess I'd say call a vet for info.

The others, I am not familiar with those.

Good info, thanks for sharing this!
