This past weekend 3 of the kittens were euthanized because they contracted
Parvovirus for which there is no cure. It was pretty rough and our home is a lot emptier now. The two smallest kittens were initially sick as well but seem to be doing well now. The vet said that they may kick it naturally. We're keeping our fingers crossed.
The pic below is of 1, 2 and 4 as they were heading to the vet. I didn't know at the time that I wouldn't see them again. Pretty cute right to the end and pretty sad looking at them again.
