Not sure about that. I think crow family (maybe magpie or jay) scared the life out of my Snot Cat (who believe me, is a big cat) mate and poor old Starboard (RIP years ago) was almost led into a trap by magpies who then mobbed him.

I have witnessed a weird friendship with Cassius (lean and hungry look) Crow and Dylan the rabbit though. Crow would tweak food out of rabbits mouth, hide it and then parade on the wall - like a guard doing a castle turret watch.

Never knew what happened to crow, except he got well and flew off. He (well I'm saying he) never was a pet but a bird we took in briefly.
