Lesley,
I suspect bdeeley's sense of humor has decided to tweak us all a bit and he was just kidding about the dogs and cats. Or at least I hope that's the case.
And with all due respect to those who hold differing opinions, I hesitate in believing the motivation behind this is purely altruistic. More like the almighty dollar, unless of course, the management will charge no admission and allow all who choose to, enjoy it for free. But even then, I would be in opposition.
I can't really relate to birds or horses but having been lucky enough to have encountered dolphins playing freely in open waters on several occasions, the idea of seeing them penned with a price on their heads (admission fees?) just doesn't do it for me, ergo I will NEVER be able to accept this, if in fact, this is what it is ultimately intended to be.
Were they planning on running a rehab lab or something of that nature I might view it differently but note, I said might. But from the sounds of things and having some idea of how generous this concern has been in the past, I somehow doubt that is the intended reality.
