The Fun Part

After the chimps take their nap and leave the cages to return to their enclosures, the volunteers (me and Iona, from Scotland) plus the 2-3 Zambian workers get to clean all the cages.
There is no running water, so we use only brooms. And the chimps really trash these cages each day.
When was the last time you tried to clean up monkey urine and excrement with a broom? It's not easy. And it doesn't smell fantastic.
At enclosures 1 and 2, we clean up after 69 chimps. That's about 10 or 12 separate rooms. Sweep the mess into a corner, scoop it into a wheelbarrow, and dump into a dry well to be burned. Then, wash your hands!

By then it's after 3:00 -- time to walk a long way back home, or get a lift from some other staff if you're lucky.
