Was at the Mirage in Vegas around 20 years ago and they had tigers and Lions on display. Heard a mournful cry from a Tiger, looked and saw some little kids annoying a big bengal tiger. The Tiger promptly turned around, lifted his tail and gave all three kids a hilarious soaking. Just another example of FAFO.
Gorillas are similarly not to be messed with ... they can throw “substances” with considerable force and accuracy.
