it's so scarey for us when we think our pet has eaten something it shouldn't have.
donna gave some great info for all of us with the site she gave you.
i know that now...when we buy grapes...we wash then leave them in the sink in a strainer to dry...we won't do that anymore in case one jumps up behind our back and decides to try one.
we'll let it drain on a plate in the fridge.

i sure hope that your kitty is ok.please please keep us posted on how she is for the next few days.we really do care...i hope she is ok.
Prayers will be on the way from us.
