Oh, no no, the 1 ball python it's just an hypothetical number to calculate.
I have more than 1 ball python. In fact, I have 17 snakes (6 adult ball pythons and 1 juvenile).
I've been breeding mice for a couple of years now and feeding my other snakes with them, but now that I have adult ball pythons I want to start breeding rats.
The main problem is waiting the rats to grow to proper size for adult ball pythons.

So, in theory, 6 female rats should be enough for 6 ball pythons, then?
