So are you saying both the ones you kept died of what the Vet said was poison, and one of the ones your daughter kept died of poison, and the other one your daughter kept died of "something", but it started just the day after her sister died?

First off, I am so sorry for all these losses.  That is so sad   

Second, unfortunately, we have no way of diagnosing anything via the internet to try to figure out what happened.

Third, have you contacted the people who took the other 3 to see if they are ok?  I'm wondering if it might be something genetic?

Again, my sympathies on your losses.
