Although I staunchly defend the right of properly trained and experienced people to interact FC with suitable adult Big Cats, I can think of no sensible reason why members of the public should do so. I am yet to be convinced that public interaction with Big Cats in excess of 20kg is about anything more than raising money. The risks are just not worth the money.
I guess the important words are " properly trained and experienced people"
On my first visit to Zion I saw one handler walking a two year old bengal tiger on a leash amongst the public, and a member of public taken into enclosures with full grown lions and tigers to pat them.
No No No!!!!
