I have pet rabbits, chickens and guinea pigs running around in my garden along with a my Westie - there is a green outside the font of ours and the same two boys keep kicking their footballl over into our garden. We've asked them to be careful as we have pets that could get hurt. The bird tables keep getting knocked over and Ive even had to remove the green house-I They've now started trying to climb over the walls by standing on wheelie bins that fall again our car. How can I stop them from doing this. I can't see why I have to leave my back gate unlocked to just anybody can walk onto my property.
