Funkadelic Rat Smell

[Herpin' Man]

Do you tease feed (i.e., jiggle the rodent so that it appears to be alive)?
If not, you should try it. If a snake is tease fed each time, most snakes will respond immediately, unless they are simply off feed for some reason.
Hog Island boas are usually strong feeders. If you are keeping it warm enough, and not feeding it too often, it should eat.
If it is simply being particular, let it get good and hungry before you try again.
