Congrats...but a lot of reluctant boas are reluctant because they are being offered mice. You will typically get fewer grey hairs from stressing over them not eating if you start them off on pink rats and continue with rats. With exception to premmies and a few very small runtlike insular locales of boas, no boa should ever even have to know what a mouse is
I have had a couple before though that reversed it all...wouldn't touch a pink rat but would scarf down a hopper mouse. They grew out of that eventually. But I've only had that happen like twice. It's certainly not normal for any boa constrictor to prefer mice. It's also not unusual for a boa to be near starving before even considering eating a mouse. Rats are better for them anyway. Get some and try it
