People who won't feed their snakes rats....

[Stewart_Reptiles]

.... Why not?
No judgment, just curiosity

Let's see because

Some snakes are stubborn and don’t switch easily or don’t switch at all.

In some areas it is easier to find mice than it is to find rats.

etc

Bottom line it's about what work and what is convenient for the owner.

Ball Pythons that eat mice do as good as any other BP that eat rats

I feed rats, mice, live, f/t; as long as it works that is all that matters to me
