Medieval?

The image below is of a trap found clamped around a cat's leg in the village just yesterday :( I have to confess to being no great fan of cats but if there's a less humane way to deal with pests then it's hard to imagine. I'm relatively certain these traps are illegal in the UK these days, and with good reason, but I suppose there are still plenty in use. This one won't be being used again thankfully having had one of its jaws removed but be warned - obviously somebody local has no qualms about setting these odious traps and inflicting immense pain / suffering at random. It could be your cat / dog next...
