snakes won't eat

[Stewart_Reptiles]

when are they expected to start eating again?

Depends on the animal and it depends on the setup. Sometimes adjusting your husbandry helps the animal resume feeding a little faster.

Generally speaking anything under 800/1000 grams will eat voraciously if kept in optimum conditions. Of course there are exception but they are obviously rare.

If the temps drop if the enclosure is too large creating stress over time, if the animals are handled too often this may lead to refusal.
