I agree with the start of that, but even as a full-grown adult, I found my girl did best on a medium rat about every 3 weeks. She was very uncomfortable when I tried
her on a large rat, so I stuck with mediums & she had a solid healthy weight, but was not fat (at 7.5'). Jumbo rats are basically retired breeders that have higher fat
content, & for that reason, I don't think they make sense to feed most boas, since their metabolism tends to be slower, but there's probably exceptions to this.
