Complete nonsense. If the tiger got out, the height is not okay. It's only within guidelines if it prevents the tiger from getting out -- like if that moat had been filled.
Re: It’s only within guidelines if it prevents the tiger from getting out
Huh?
If the height was within the guidelines, the guideline may have been wrong, but said height was still within the prescribed height so it would be in fact “within the guidelines”
Get it?
They are given “suggested guidelines”. There is no hard fast requirement to have the enclosure x feet high. They’ve had this exhibit for YEARS and when people don’t taunt them, all is fine. Even kindergartners see this exhibit and don’t get attacked ... .
