One thing though, you do realise these have very slow matabolisms and take long to digest food. I don't know if i have read wrong but you fed him/her a weaner then 5 days later a rat, if so then sorry but that is flipping crazy. I am extremely suprised that s/he has copped with that amount of food in her in such a short amount of time. If i am wrong then apologies but if not then i would reconsider looking at some caresheets as you will end up harming this beautifal boa.
Sorry for the negativity but i am thinking of the boas well being here.
