i dont think they would either,i actually looked up weather in columbia,and it appears florida is much hotter,but not as humid,but i just dont see them thriving,especially in a city setting,,just doesnt seem possible,,,and i am aware of thier size,and i know females can reach 12ft,and realistically,a smaller person,or a child,would have something to worry about,if it was a pissed off boa atleast,but moan boas dont have that mentality,or atleast most i have handeled,,and i am pretty positive a 9ft,healthy boa,would have no issue with the average size cat,as a lot of thier ehight is purely legs,same theory as a burm taking down a deer,when the car is laying down next to a rabbit,,there isnt such a size differenct to make it not be plausable
