Somebody who gets it!
Though I'm not surprised at all seeing as bcr229 keeps a wide variety of species.
I will say at times I will feed my boa a rather large prey item, but this is followed by AT LEAST one month with nothing, and usually preceded by a meal that would be considered undersized the month before.
My BC will not eat at all from November to April and I use seasonal temp drops and decreased lighting during the winter months.
As bcr229 stated boa constrictors are usually overfed. I'd bet 95% of all captive BCs see too much food.
I was certainly on that track myself early on.
Your snake, OP, looks to be in very good health at least by looking at the body.
I think after the vet check you'll be all set!
