They haven't been to a vet yet. I'm not sure but I thought at their age they would still be too young for deworming? The runt still has her umbical cord attached and their eyes are still closed. They have done so well this weekend, that a part of me is very devastated I have to give them back. The black male has been making some sniffing sounds so I hope that he is not getting a URI. He has been eating, pooping, and peeing so those two ends work well. I don't think I've heard him sneeze, but am concerned about the sniffling.
