I think your best bet would be to get or make a small device that lights up when audio is present,
and put "THAT" in the cage with the animals and visible to the cameras.
I'm sure there's a small project like this on hobby websites. It could prolly even be battery operated.

Just my thoughts on how I'd tackle the issue..
