Animals are not exhibits

Could you let me know on what planet is it ok to get up close and personal with a nursing mother, especially when that mother is a wild animal?

If you must do ‘special’ tours, then leave the nursing animals off it. !It is unfair to the animal, and dangerous to anyone nearby.

The animals are not exhibits, they are living creatures. Does this really need to be said? I am surprised and disappointed at Dublin Zoo.
