I would also check the money trail, ( I presume you have to pay to go in ? ).
'Most' Foundations aka Charites I don't trust, with the 'donations' given to them, paying huge wages to themselves, and live in luxury accommodation, even the Trash Hero's, dog rescue places, and Elephant camps, ( like the Swiss man paying 1m a month rent.) I know there are many that do real good and benefit the HUMANS they are aimed at.
