The deer felt nothing.
A severed spine cuts all sensation.
5 minutes is nothing.
Did you sit quietly while he died or did you go to him?
The only suffering would be from fright from you standing
over him and not being able to flee.
Another arrow would be unnecessary.
Slitting the throat would be unnecessary.
He had no idea what hit him.
Aim for the vitals next time.
I shot my first deer in the earhole with a 30-30.
I was inexperienced and was looking at horns and
hit where I was looking.
That is what you did.
Congrats...eat him up!
