And even if an adult female has passed away, she may still have living babies inside her pouch.
It's in the sticky, but just in case anyone hasn't seen it:
DO NOT try to remove those babies from the pouch! Just place mom in a box or something and take the whole lot of them as is to a rehabber.
The babies jawbones grow around the teat so they don't detach. Removing them improperly will cause those babies some big problems.
