Hope he recovers! Did he seem to have any wounds? It sounds like the cat just got mostly feathers...
How awesome of you to save his life. He would have died for sure if you didnt help him!
Im the same way though...I rescued a baby dove who fell from the nest when I was younger, took him in, and took care of him until he was full grown, and then one day...let him fly away. It was awesome. He would have been preyed on for sure..
