Haley once got into 2 different full bags of those (after eating several spring onion stems I dumbly left where she could reach- her mouth was probably hot I guess), the citrus and the blue "super-menthol" ones... she apparently decided halfway through the bag of blue ones that they really weren't all that good, so crunched several of them up all over my bed, sticky, sticky! No ill effects, and she's got a pretty delicate digestive system

. I think some of them also have pectin, which I would speculate would help with the digestive aspect of it. Maybe.
