He has always been aggressive, had him since he was a kitten, so for 5 yrs. We have always treated him well, he has always been well fed and healthy etc.
I have tried to find ways to deal with his aggression but none of the "triggers" apply to him. He just randomly bites or scratches with no warning and runs off.
This week he has woken both my DC's by biting or scratching them when they are asleep in bed. They sleep with their doors open.
I don't think he could be rehomed/rehabilitated, so I think I might need to euthanise him.
