Boas metabolism is very different than ball pythons, boas is much slower. They can become obese easily too. It is said to be best to slow grow boas. So you don't want to feed a rodent that will leave a bump. And yes, feed an adult every 2-3 weeks. Boas are awesome though, I love mine. And he is very docile, much mellower and more easy going than my bps.
