All of my Colombian males are under 5 feet and barely 5-7lbs. They are lean mean breeding machines, lol. I'm a firm believer that a male colombian boa doesn't ever need to go off medium rats. Hogs are not a step up from BP's, they are fiesty little buggers and hiss and bite quite randomly. All of the above named Island and smaller locale boas are the same way. When you start to get locale specific, imo, they tend to get more and more intermediate level. Good luck!

psst..get a colombian...lol
