Byron has wandered the whole house and gained an ounce. Buster is still mostly sleeping, has a fair amount of eye discharge, and weight is back down. But no fever and he's still eating. I think he just needs time to get better. Both of them have imprinted on me and would just as soon follow me around or sit in my lap than anything else when they are awake. Bigs seem to be accepting littles as part of the new routine. If nothing else, they are interesting to watch when they finally get to explore the house.
Update on Group 1: All pictures have been removed from the shelter web site. That most likely means that all have been adopted.
