I know pal but I had one chase a doo into a window the other night, the doo died outright and percy was sitting on it in the neighbours garden. Also had one hit a roller years ago, was told they clench their front tallons to punch the doo and their back tallon rips the doo open. The roller landed in the garden with its neck ripped open. I binned it so dont know if it might have come back.
