OK, I have to put in my two cents here...

They have done a LOT for tiger rescue. While I am against the exploitation of wild animals for entertainment, these tigers live VERY well. Unlike most entertainment animals, these tigers live in a sanctuary that my house could fit in several times. None if this changes the fact that Monticore is a wild animal.
(Roy has said this for years BTW...he KNOWS the risks he is taking)

Roy is still critical, but has started speaking to people, so he's improving.

What happened was this (Getting this info from another forum BTW): Monticore was noticed to be limping slightly. Roy told him to "sit", and when he did not sit Roy tried to gently push him into a sitting position. When bitten, Roy thumped the tier on the nose to try and startle him into letting go, but the microphone in his hand made a "boom" noise, and the tiger did as he should be expected to and attacked the source of the noise. After that, he dragged Roy offstage.

Montecore is not going to be put down. (Huzzah!)
