Glad to hear yours are all better too These URI's can be nasty and are soooo contagious. Extremely bad in shelters, animal control facilities and even breeders that have too many in too close quarters. Unfortunately, it's viral so other than preventing bacterial infections it pretty much has to run its course, just like in us humans It's really tough to prevent when, like me, there are so many (9 of my own-I'm still working on the pictures) and a couple of fosters and always bringing sick ones home. Vaccinating helps but still will not always prevent it, depending on the strain of virus.
But with lots of TLC like y'all have been giving, your babies will be just fine
