A small rat weighs between 46 and 85 grams from most suppliers. If your snake just ate one and hasn't pooped yet so the 110 grams isn't an "empty weight" then it's overfed. Get an empty weight on it and then figure out what size feeder it should be taking. Up to a year old they should be on a 10-14 day schedule, then I add a week for every year they age until they reach adulthood. I feed adult females every four weeks, males every 5-6 weeks.
Boas also should not be fed heavily as being fat can cut their lifespan in half. They also are opportunistic and unlike ball pythons will "beg" even if they just ate yesterday. For babies I want to just barely see a lump, and adults get a rabbit whose thickness is about half of the snake's girth.
If yours has a strong food response I would suggest starting to tap train it.
