I called the emergency on=call vet. They said one would be toxic cause she is so small and to give her 1 tsp of hyroden proxide to make her puke. It worked and she puked up alot of stuff. I hope she will be ok, they said as long as I could get her to puke she would be, but if I couldnt get her to puke to bring her in. I feel so bad, she puked and dry heaved. Poor baby. Hubby feels bad, but he had no clue grapes were toxic. Gotta go, she is puking again..
