You could poison 'em, you could gas 'em, you'd probably be put in jail if you borrowed a jack russell and a 12 bore.... or as we have for the last 20 years you could live with them. It is a pain. They crap everywhere, ours waltz over the veggie beds as if they owned them, they wear tracks round the lawns and when they are feeling amorous they will most certainly keep you awake! But the cubs are cute and our nephews are convinced we have wolves at the bottom of the garden Now the parakeets are another matter.....
