Yeah, I was just going to add that breeding (any kind) of rodents to feed one (or a few) snakes is probably not cost effective or a good use of your time,
unless you'll enjoy doing so & have an outlet for excess & inconsistent #'s of offspring. You have the cost of caging and water bottles, the breeders them-
selves, litter & food to consider...larger operations are just more efficient; also, if you like them enough that the breeders are actually "pets", how will you
feel about stealing their children to feed snakes...I'm not saying you can't do this, but we're all different & it's better to think about it now, than later.
Also, do you have a good place to breed the rats? Rodents contribute a certain "je ne sais quoi" to the air you breathe...
