So, sometime in the middle of the night, Twinkie stole one of Princess' necklaces off my nightstand and chewed the crap out of it. In doing so she chewed off some rhinetones. I could only find 8 of the 12 rhinestones in a pile - 1 of which was severely mangled. The other 4 rhinestones are missing so I am assuming she ATE them (they are about 2 mm in size). The rhinestones are GLASS since they are crystal - should I be worried that she ate glass??? Will it just pass through her system, will it hurt her? She doesn't appear to be in any discomfort, but I am worried anyways.
