Never shot a cat broadside but would imagine I would want to go behind the shoulder, 1/3 up the chest due to their more posterior heart placement. Read somewhere shooting at a cats anterior shoulder may cause trouble with a possible missing of enough vital structures.Is this correct?

Shooting at the "hinge point" of animals shoulders should get both lungs with a higher shot and certainly be fatal. I have shot and lost an elk with anterior placement of such a shot by a scoped rifle and after tracking it all day I was not a happy camper.My concern/experience would be such shots can miss the lungs on elk while shooting lower and a touch posterior anatomically might get the shoulder bone and both lungs, or the great vessels/heart region. Kinda like hitting the trifecta if you get a shoulder,both lungs, and bone fragments to the great vessels.I doubt you could count on bone fragments doing anything on Buff or Ele though--
