Thankyou everyone for the valuable information on these websites..through these we were able to find out that the species they ate were not poisonous! But man, did it scare me! Especially our new baby!!! She was the one eating the fastest!!! They were growing in the potty box my husband built them on the balcony...so no more going outside until the box is inspected..actually I think I'm going to pull the grass out until we find some more sod..its not worth taking a risk..it could still grow and produce something poisonous to them!! I am grateful to my responders here
