Well, we had to hold her down and pump hydrogen peroxide down her throat last night and she puked up most of the poison, but it was digested a bit so she definitely absorbed some. We took her to a spendy emergency vet visit, and she got a shot of the vitamin K antidote, but then when we got home she puked up some blood, which has us worried, but the vet said there is nothing else we can do at this point. She can't keep any food down, and the pills we need to give her we can't give her until she can keep stuff down. I guess we just need to watch her and hope she can eat soon...
