I have one that only eats in July and August for the past 2 years. The others usually only go on a 1 or 2 week strike, but I guess it's the time of year because all of mine over 800 grams have been off food for the last month (some a little longer). Most of them eat F/T and that's a lot of wasted rats. I've never owned a boa that skipped more than 1 meal and that was when they were shedding. And you're right they do a lot more stuff than BP.
