You are overlooking the hundreds of meters of rockface the poor squirrel will have to climb before it can reach any area where the possibility of food and water may exist.
None of either at the bottom of that canyon.
Perhaps thousands of meters. If it survives.
I’d like to see the arse’ole who did this disgusting deed kicked over the side in the same manner and then attempt to try to climb his way back up to provide an example of what he so casually doomed one of Gods creatures to.
I’m guessing he would not make it.
Does that make it bad that I hope he does not? *thoughtful grimace*
