You can work alone with big cats (along with other dangerous animals as it happens), slides may be on a colour coded system such as red and black. So when the red slide handle matches up to the red lock on the wall, it means danger and slides are open etc.. I often find working with 2 people is more worrying.
On the note about leopards, they are also very dangerous, a pair got out at Bristol zoo once and were walking along the top terrace apparently! must of been a quiet day......
