I'm so sorry to hear about this I'll be keeping your babies in my thoughts for a speedy recovery!!

My friend's dog was killed from rat poison about 6 years ago. We went out to her friends' ranch and came home to Ginny bleeding in the kitchen. She was moitionless, but still alive. We rushed her to the emergency vet, where she died over night. They determined it was rat poison, which my friend's mom had put out in the backyard that very day.
