I'll concur... Most rescues (including my own) wouldn't adopt out to a family that is currently breeding rats for feeders.
Some may see that as unfair, but think of it from our point of view - how do we know that the rats we adopt out won't be used as breeders?

We are in the "business" to get these rats that often have come from horrid conditions into good homes.
I commend you for wanting to rescue... Obviously, I encourage that.
But given the "business" of your family, most rescues can't trust that the rats they adopt out won't be bred, or will be kept in the best conditions.
