What critical rule governs the maximum size of live insects offered to a crested gecko to prevent blockage?
Answer
Never offer an insect that is larger than the space between the gecko's eyes.
When feeding live prey, the size of the insect is a paramount safety consideration, especially concerning the risk of fatal digestive blockage. The established guideline mandates that the insect offered should never exceed the measurement of the space between the gecko's two eyes. If an insect is wider than this dimension, the gecko's digestive tract lacks the necessary diameter to successfully pass the item through peristaltic action. An insect too large will lodge in the tract, resulting in a severe and often fatal impaction.
