Three sodding massive magpies have moved into our garden and taken th picking on my cat. They fly right near him, making their awful chattering noise and they peck him and swoop away. As soon as he goes out, they go for him, and it doesn't matter if he's in the front or the back garden. They'll find him and peck him.
It's clearly stressing him out, and he's been spending loads of time indoors, when he loves being outside. Is there anything I can do to deter the evil bastards?
