No need for apologies AFAIC.  I completely agree.  Anything that wants to hurt my animals and doesn't take a warning to heart has forfeited any rights it had in my opinion.
I just saw a baby opossum running across the snow and under my shed this morning.  
		
		
	
	
 It got away before I could get it, but I'll be watching for it and the rest of the family now.  It was small enough I know there is at least a momma and maybe siblings around too.  
  Got rid of the dang skunk and now I get possums.  
 
 
ETA:  The barn cats take care of the mice, rats and voles.  But I think a possum is a bit much to ask of them.
