This is not to raise the spectre that the situation is dangerous right now. But it is right that we should understand that there are indeed risks to living alongside these creatures that can prowl unseen in and out of our communities. Foxes have lived in our towns and cities for years. Big cats are now being reported in and around London more regularly. To eradicate the big cat population will be massively expensive in time and money, purely because they are so difficult to track down.
Nobody can just go out and find a large cat to order.
In practice, culling will most probably be attempted when the police judge they have a serious situation, and not before. I am already confident that measures are in hand within Police forces throughout the UK to shoot if circumstances justify it, and the right opportunity permits them to do so. Please do not attempt to shoot a big cat yourself. A wounded animal is extremely dangerous. People have been threatened.
