Central Americans Muskier? Or no..

Is it just me, or are CA's more musky than Colombians or BCC? My three new 2011' Nics have recently made messes of their quarantine tubs after eating last week and wow.. It seems much stronger to me than my BCC and she is much, much larger. I even bathed one of the females with a bit of dawn because her paper towels were half soaked urine and she smelled very strong and of musk. Not an ammonia urine smell. A musky smell. I was immediately reminded of some colubrids musk.

Are different locales muskier than others? In the years I've kept snakes Ive only ever kept Colombians or Surinam so I've never noticed an odor difference before. Has anyone else noticed this with boas?
