Looking for an old school Rat trap.

You have a rat IN your home or outside?

Please try a method that doesn't involve killing the creature. There are humane traps (I know, an oxymoron) such as a cage trap that don't snap shut and maim or injure the rat or electrocute it. Normally other animals in our ecosystem would keep them under control, but humans have invaded so much land and displaced so many other animals that we need to be more careful. Ferreterías and veterinarios usually carry these, but they are also available online.
