How long before new snake eats

[Carito]

Hello everyone. New here. Well after a long hiatus, I've got me another snake. Haven't had one in quite a few years. So it's been a while.

Anyways I just got in Tuesday 4 days ago, a female Hog Island Boa. She came with her feeding card and looks quite healthy. Tried to feed her a couple babies today but she wasn't remotely interested. Now I've never purchased an animal overnight so maybe some of you know. About how long should I expect her to go before she resumes feeding? Should I keep trying every couple of days or so or just wait till some time next week?

Thanks for any advice you have,
Carito
