Die Hard

These mice are very hardy now. Its means they live longer than I expect them too. I usually can predict how long they would live after I innoculate them with my parasites depending on the how heavy the dosage is, usually about 4 days. Somehow now they can live an extra 2 or 3 days. I need to know the death date so that I could salvage their peritoneal fluid and infect other mice. It would be very inconvinient to have them die on a weekend. So I try to make sure my next innoculation would fall during the weekdays. I think due the constant exposure to the mice, bedding and feeds, I am getting allergic to it. Now I have to take extra precautions to ensure none of those touches my skin.
