Does anyone have ideas on how to manage feral cats populations near zoos, especially how to keep them away from kangaroo enclosures? What deterrent methods won't bother the big cats and would be realistic over a large area? Bonus points if you know of successful humane methods in use by a zoo.

HI Beth;  I noticed no one has responded to this question so it means it is a good question.  Did you solve the problem?  How many cats are you talking about?  Where are the fed?  Where are you located?  I can brainstorm some ideas,  but would need more info.
