I'm thinking of encouraging my son to use his bow and arrows at the local cat shelter.
That seems foolish. Why would you have your child use a weapon around innocent animals?
I hear stray cats don't become angels when shot with arrows.
Seriously, you want to encourage your son to kill homeless cats? That's horrifying and could get your son in serious trouble.
I want him to test my arrow's aim.
There are ways to test out a bow and arrow without anyone getting hurt. Have you tried going down to your local archery range? Even setting up some targets in your backyard is smarter than hurting innocent animals.
