Sheesh! Did you ask if there was a number of a vet that helps with these sort of things that you could call? My Ext. office put me in touch with the head vet up at VA Tech. He is completely awesome and super knowledgeable, just extremely difficult to get ahold of. Sorry for the disappointment on that one. I just wish I could help you figure out what is wrong with your babies. Worms can cause diarrhea and weakness, so that's why I went with that initial diagnosis. If they aren't sneezing, wheezing, or coughing I wouldn't think it was anything to do with any respiratory illness. It must be something intestinal. Keep me updated on how they do.
