Leopard Gecko Dropped Its Tail: What to Do and Will It Grow Back?

Why it happens

Many lizards, leopard geckos included, can drop their tails on purpose. It is called autotomy, and it is a defense against predators.¹ The tail has built-in fracture lines, and muscles around them contract to release it.¹

ReptiFiles lists the usual triggers in pet leopard geckos:²

• Stress or fear
• Being grabbed by the tail
• Stuck shed around the tail
• Illness
• Bullying by a cagemate

PetMD adds that malnourished, sick or weak lizards drop their tails more easily.¹

The first hours

• Do not panic. It is not a life-threatening injury, and there is usually little or no bleeding.¹
• If the stump bleeds, press gently with a clean towel or gauze and take your gecko to an exotics vet.¹
• Swap loose substrate such as sand, soil or moss for paper towel, so debris cannot stick to the stump.¹²
• Keep the enclosure very clean, at its normal temperatures, with fresh water and a hide.¹

Should you treat the stump?

The sources disagree:

• PetMD advises against cleaning, bandaging or applying ointment, because it can interfere with natural healing.¹
• ReptiFiles suggests a disinfectant such as povidone-iodine, or a triple antibiotic ointment.²

The biggest risk after tail loss is infection.¹ If you want to apply anything, ask your vet first.

Feeding while it heals

A leopard gecko’s tail is its main fat store, so losing it means losing reserves. ReptiFiles says the gecko is more vulnerable to illness until the tail regrows, and suggests feeding more than usual for two to four weeks.² Vet Times advises feeding daily while the gecko recovers, but not feeding crickets, which may injure the open wound.³ Keep dusting insects with calcium.

How it grows back

• About 7–10 days: a thin layer of skin covers the stump.¹
• About a week later: the spinal cord begins to regenerate inside a tube of cartilage, because lizards cannot grow new vertebrae.¹
• Weeks to months: full regrowth.¹ The new tail will not look the same as the original:² it is often darker, may lack normal scales, and is less flexible.¹

Preventing it

• Never pick up a leopard gecko by its tail. Scoop it from below.¹
• House it alone. Bullying by a cagemate can trigger a tail drop.²
• Give it enough hides so it feels secure.¹
• Check for stuck shed around the tail after each shed.²
