That's what worries me about people coming to my house to collect stuff, for example if i've sold something on ebay...you never know who's going to turn up, and they or their mates might come back later for my dogs, my ferret, my chickens, or anything they've taken a shine to....i keep the dogs locked away when strangers come here, you wouldn't know i had any
CCTV, security lights, infra red motion detectors that send a chime to a receiver in my bedroom, padlocks, bolts, 2 lines of thorn bushes out the back fence...and i still worry luckily if anyone's about the dogs kick off big style
