I killed a mouse this morning. We had set some traps last night as my wife had spotted a mouse running around. Came into the kitchen this morning and spotted a mouse lying beside the trap. Excellent, I think, the trap has clearly done its job. I then go to bag it and bin it when it starts moving and I am a bit taken aback. Then starts a bit of thinking about how to humanely put it out of its misery. Do I just put it in the wheelie bin and let it die, clearly in pain and unable to move? Do I take it outside and let the local cats finish it off? Do I end its suffering by smothering it with a pillow? In the end I smashed it with a brick and now I feel terrible.
