Help with poo

[Fiona]

I'm new to zoo tycoon 2 and am stuck, I keep getting messages that the zoo keeper can't reach (whatever) poop. I've no idea why or how to fix it. I have enough zoo keepers and they are often in the enclosures when it happens. Help! I'm sure I'm doing something stupid but no idea what to do

Not much you can do, the zoo keepers seem to have trouble figuring out how to get around that tree or rock to clean the poo then just give up. What I do is drop down into guest mode and clean it up myself to make the message go away.
