I had to go out of town for a week, while I was gone my brother said that Hampton and Carlos were hardly eating or drinking, this really worried me. I can hardly believe him, because now that I am back home they seem to empty their hay faster then ever. I'm not sure what is wrong with them... I am worried because I have to go back out of town, and I don't want them to get sick while I am gone because of not eating... Advice?
