I've only hit a roo and a calf on Outback roads. The calf went under the vehicle after hitting the bull bar and we put it down. The roo bounced off and to the side. I could not find it in the dark as it must have moved off.

That moose hot was spectacular, but I doubt the poor beast survived it even if it did walk off.

Same thing can happen with cattle in the outback. Worst of all is hitting a came;. As they supposedly easily end up on the windsreen and cabin. One reason most non trucks do not drive at night.
