This January I bought a 08 1300 grams female normal ball python. Former owner say's that she is a rat eater but from now she didn't eat a rat( former owner says just give small rat or rat pups because sometimes they're intimidate). She like adult mice but I like to switched it to rat.

I'll do many tricks like mice then rat, rubbing the mice to the rat to get an scent but all fails.

I did not give a live prey in all my snake for security reason.

Any tips or opinion on how can I switch it.

Thanks!
