It's cheaper to buy bulk FT online. Just saying.
For one snake, easily get 2-3 litters and it's enough for 6 months. If that's the way he wants to do it, fine. However, you did not initially expand on how he could go about it, but thanks so much for letting him glean more information from you. This is a much better plan than just letting two rats breed constantly.
I even have a guide I've written up with that method in mind; here and on my own site. I'm no stranger to it.![]()
