Hi Irene,
Id be worried about intestinal blockage if they eat too much.
With paper thats like newspaper I'd be worried about it turning to paper mache and sticking to the roof of the mouth, then coming away in one lump and them choking on it. However if its a 'teabag' type paper this may not happen.
If your concerned then dont use it, better to be on the safe side!
