Personally, I'm worried about snakes that have only eaten ASFs and nothing else. I live in a state where ASFs are illegal. So finding an ASF source just in case the snake doesn't take a rat our mouse is nearly impossible. I do know *one* source. But they price their underground ASFs at $25 a pop.
Hardly worth a feeder in my opinion...
So I'd rather just not take the chance and buy a strict rat/mouse feeder.
I would have no issues with ASFs if they were more abundant in my area ....
I would actually prefer to breed them over Norway rats.
