When i was like 10, my neighbor rescued a baby screech owl being attacked by his cat during a bad storm. It was a little poofball that was pretty much helpless. He didnt know what to do with it so my dad built a cage in our garage out of 2x4s and chicken wire. We put in some branches and we fed him and took care of him until he was healthy. We mostly fed chicken liver and it would hand feed. It was amazing how smart the thing was too.
We would wear leather gloves and let him fly around a bit in the back yard and it would always come back to us until it was strong and healthy enough to leave for good. It was very cool experience, needless to say all the kids at school were jealous.
