I agree Dalerite, I think Zoos in general are horrible places and to cage up great big creatures like the Orca is somewhat barbaric.

I think I am right in saying that the whale used in the Free Willy films died a horrible death after they tried to get him back into the ocean.
I still remember years ago the pathetic sight of Guy the Gorilla at London Zoo
and vowed then never to go back to the place again.

Perhaps wildlife parks are a little better and if we wish to stop wiping out our animals I suppose we have to keep them in captivity.
It is still sad to see though.

I have never agreed with the caging of any Birds or Animals, on the grounds of Cruelty. If those owners, were to be caged for a period of time The Complaints would be numerous. Even criminals are not caged and possibly deserve that type of treatment, when having Inflicted Bodily Harm. Then listen to the call of "Human Rights" 
Even that Police officer, that left those Dogs inside his car, in such Terrible Heat, were they Both Died, has not been given any severe penalty. Where is there any Justice.??
