We are sorry for your loss, never easy to lose one any way, but especially to a free loading predator. Just baffled by a few that question the fact that
A - You caught the perpetrator
B - It left olfactory evidence
C - You caught a second one...
...I agree with the way you disposed of the issue, even though others may not. Perhaps they would think different if they walked in you shoes. Had you relocated them, they could have become someone else’s same problem...unless you have someone you would wish that problem upon.
