Poor, poor little Tweeker. And poor us! Never more shall we hear of his/her amazing feats of escapism.
I know that what you did was the right thing to do PF. No one ever wants too see an animal suffer, especially not when we're in a position to show mercy and end that suffering. I so wish it could have had a different outcome for Tweeker, but I'm sure this was all for the best. As another member once said: "Some of these little souls are just to precious for this world" Farewell Tweeker. Rest in peace little baby, rest in peace.
