I don't see anything that suggests a SINGLE ball python needs to be fed in a side cage. They are saying that IF you house 2 of them in the same cage, you
would need to feed them separately in other cages...They've got all kinds of garbage-information in this article...and remember, they are in the BUSINESS
of SELLING you accessories for your pet...like those extra cages. Their instructions should be flushed...whoosh!!!
