My 4 babies are nearly weeks old now. One of them started looking hunched and sneezing a few days ago but is still alive and running around and then this morning when i looked in on them another one is looking hunched and they're all sneezing! I dont know what to do. If i go to the vet with all of them its gonna cost a fortune plus my vet has no idea what to do with mice. I've taken all wood shavings away in case that had something to do with it but they seem worse every time i check on them. Im worried im gonna lose all the babies. They're still running around and eating and drinking, is there anything i can do?
