My cat brought in a mouse a couple of days ago, and I found that she'd wounded it to the point where it was still alive but couldn't move it's back legs.
I caught and released it into a nearby field, but I'm worried I've sent it to a long slow death, instead of a quick one by my own hand - which I just can't bring myself to do. Was I unreasonable? What's the most humane thing to do here?
