The hedgehogs in New Zealand are not very popular because they are an introduced species. As is often the case with introduced speces, they did very well there and became a pest. They have a lot of ground nesting birds, there – hence the problem. Thankfully these days, people are more careful about introducing animals to places where they don’t belong – I hope!
I agree – seems strange they don’t like hedgehogs in Saudi Arabia, if they eat the pest insects. I am assuming it is a species which does belong there.
