and
Buddy
In addition to the usual array of considerations that are, unfortunately, a "must" anywhere today, even out where we live, our security has long been assured by an array of highly trained and motivated killers including....
Booger and
Buddy
who've gone on to a 10th life.
And
old Nick 
who's,
no doubt, chasing deer all around heaven.
Then there is the current platoon of ever alert guardians like....
BlueCat 
(ask
Willi, not me, to explain that name)
Butter
(shown here in his deceptive 'possum' posture)
and the last line of defense.....
Billy 
and
the ever cunning & lethal BRUTE.
