Metal detector

We have a metal detector at home. Anybody who lost nails or anything similar should contact us and we can lend you our Super-Iron-Detector. Given the price of iron ore maybe we should start a scrap metal business with all the things coming out of nowhere ending up in the house.

How on earth does this happen?

Chatouille's catflap is operated magnetically. She has a magnet around her neck so that not all the cats in the neighbourhood can come inside our house. This magnet releases another magnet placed just below the flap and unlocks it when Chatouille points her nose throught 'the tunnel'.

The problem is, she is picking up all sorts of things, mostly nails, which sometimes hang dangerously on the magnet around her neck... until we spot them and dispose of them. They also get caught in the flap itself, preventing Chatouille from going in/out.

Where does she find these things??? We have cleared anything that was visible to us, most of the nails were from the shed, which we had re-roofed some months ago. I really hope she will not hurt herself, this is quite scary to think of this. Look at the size of the nail on the photo! Who wants that around one's neck!!!

Occasionally, we hear a "cling" noise, and it is her magnet being attracted to a chair leg, or the fridge... this is hilarious!
