Petting zoo's

Hello,

I am currently enjoying some vacation days with my family and today on our agenda was a petting zoo.

When we arrived it was a crazy madness of children happily running around laughing and screaming. Parents looking proud and enjoying themselves with their kids. Allround hapiness.

I started observing the animals and started wondering if they too had a jolly good time.
I saw goats being chased by hordes of wildebeest (kids). I saw a duck trying to both escape the madness and look After her offspring. Then I saw that the only moment the animals seemed to cope with this was when they Got Food from the children. Either there are tranquillizers in it or the animals get bribed :)

Anyone else do think this or is my imagination too vivid?
