I worry for the state of the lions in that zoo. Unless they were brought in with all those scars they should not be looking like that if they are being cared for properly. Also, they said that those in the "holding cells" were the ones that were causing trouble/fighting and separated from the rest, if that is the case, why are the three "troublemakers" being held in the same small room? All the males looked really scarred and angry.
