Touch wood that you will be there for a long time! If you are thinking of living in the zoo... you should consider this.
Firstly; If you get eaten... you won't be there for long!
And..... As a zoo keeper you will have to wade through animal dung throughout your working hours! Why would you want to take that aspect home with you as well during your free time?
Start as you mean to carry on..... Don't live in the zoo.... get a place near the zoo, so you can step out of the very demanding environment every now and then .... if only to shake off your boots! Good Luck.
