i have never seen that done in australasia before, but have seen a few done overseas
mainly with cats used for mixing with the public, claims to justify it were that it was safer for the public and stopped the cats from injuring each other when fighting
all cats use the front paws to pull an animal in, hold it then deliver a bite from the powerful jaws, usually a choke hold
they are just like housecats some are laid back and will never put a claw out while some will hook in as quick as look at you
the ability to understand the mood of the animal and not push it to the attack point is rare and even those training big cats for years have been caught
the 2 magicians siigfried and roy, being a prime example of a tame tiger,
playing up in the first show, then being used for another show a few hours later
he baulked at walking onto the stage so the trainer forced the issue with a tug on the chain
that cat turned on his handler so quickly that attendants were unable to react fast enough to stop it inflicting major damage from one bite to the neck
the trainer recovered but will never be the same again
one famous tiger handler had told his family that if he was killed by one of his tigers that they were not to kill the tiger as it would be his fault if he was killed not the tigers
he was killed by his favourite tiger
