According to this FAQ: http://www.ball-pythons.net/forums/s...ad.php?t=31106

Rats are weaned between week 3 and ½ to 5, but they are sexually mature at week 5 to 6?? Meaning they can get pregnant almost right after weaning?? Is this really possible?

What is the ill effect of breeding too early, before the 4-5 months rule?

Thanks.
