What heuristic determines the maximum acceptable diameter for a prey item, such as a lizard or mouse, offered to a Wolf Snake?

Answer

No more than the widest part of the snake's body at that point.

A widely used guideline for determining the appropriate size for any feeder item, whether it is a mouse or a whole lizard, is dimensional. The diameter of the prey item should explicitly be no greater than the widest circumference of the snake's body at the point where the prey will be swallowed. Adhering strictly to this measurement guideline is vital because offering food that is too large significantly increases the risk of the snake experiencing regurgitation. Regurgitation is a highly stressful event for the snake and can be associated with various subsequent health complications.
