This page goes through the different reasons why cats may sneeze, and tells you what you should do if your cat has started to sneeze a lot and you're not sure why.
Replies to: Summer Internship Length? I don't know what specific firms policies are on this sort of thing but summer internships typically last 10 weeks and I don't think they will want to bring you on if you're going to be gone for 4 of those weeks.
However, the intern must have at least 52 weeks of individual supervision (not necessarily consecutive). Each week of accrued experience requires an hour of individual supervision or two hours of group supervision. It should be noted that these requirements apply to hours earned in 2012 or later.
