Was feeding geeses and one of the greedy ones reached up and nipped off about a 1 in by 1/2" piece of the paper towel in my hand. I know paper towels aren't as disolvable as toilet paper and am now worried!!! It seems like it would just pass through her without issue... it was only 1" by about 1/2" - she just took a bite / nip out of the paper towel in my hand!! HELP - should I be worried???
