How should a keeper determine the appropriate size of prey for a Vine Snake?

Answer

The width of the prey item relative to the snake's widest point

Determining prey size is based primarily on the width of the snake rather than its total length. The prey item should be either the same width as the snake or slightly smaller at the snake's widest point. Using this measurement ensures the prey can be consumed safely without the risk of regurgitation, which is particularly important for juveniles or stressed individuals just starting to feed.
