As mentioned up-thread it aint that simple.
What if the bunny corpse bounces off the nose wheel and gets sucked into an engine or the bird has flockmates swirling around the touch down zone?
I'm very relaxed about those slight risks. A bird/bunny strike on the landing roll will not hazard an aircraft. A bird strike on the G/A may well be a hazard, as may the resulting low fuel situation.
It's perverse to order a G/A due to a dead animal when every landing carries a fair risk that there'll be a live bird/fox/bunny on the runway. A live one is far more likely to end up in an engine than a flat one and even then, the risk is financial, not safety, unless you try to go-around into a flock.
