Common Reasons Why Leopard Geckos Stop Eating

Leopard geckos are known for their steady appetites, so when one suddenly stops eating, it’s natural to worry. Is something wrong, or is it just a phase? Let’s explore the common reasons why leopard geckos stop eating and what you can do to help.

1. Shedding

Did you know leopard geckos lose their appetite when they’re about to shed? It’s a normal part of the process. During shedding, they focus on consuming their old skin, which is rich in nutrients. This can leave them uninterested in regular food for a few days.

Look out for dull skin or a whitish appearance—it’s a clear sign a shed is coming. Make sure their humidity levels are right, as this can make the process smoother. A simple setup for a humid hide can be a lifesaver.

2. Stress

Stress is a common appetite killer for leopard geckos. Have you recently moved them to a new tank or introduced a new pet nearby? Changes in their environment, excessive handling, or even loud noises can make them anxious.

Signs of stress include hiding more than usual, erratic movements, or lack of interest in exploring. To help, ensure their enclosure is set up correctly with plenty of hides and minimal disturbances. Our guide on how to monitor your gecko’s behavior can help you identify and reduce stress triggers.

3. Incorrect Temperatures

Leopard geckos rely on heat to digest their food. If their tank isn’t warm enough, they may stop eating because their bodies can’t process food properly.

Check their enclosure’s temperature with a reliable thermometer. The warm side should be around 90°F (32°C), while the cooler side should stay between 75°F and 80°F (24°C–27°C). A floor heating setup is ideal for maintaining consistent warmth.

4. Brumation

If it’s winter and your gecko has become lethargic and uninterested in food, they might be brumating. This is similar to hibernation and happens in response to seasonal changes.

During brumation, geckos conserve energy and eat little to no food. This can last several weeks. As long as their weight remains stable and they appear healthy, it’s nothing to worry about. Keep offering food, but don’t panic if they refuse.

5. Illness or Injury

Sometimes, a loss of appetite can signal a more serious problem, like an illness or injury. Respiratory infections, parasites, or impactions (blockages in their digestive tract) are common culprits.

Symptoms to watch for include:

• Lethargy
• Visible swelling
• Mucus around the nose or mouth
• Difficulty passing stool

If you notice these signs, consult a reptile vet immediately. You can read more about caring for a sick gecko in our article on top tips for caring for an unwell leopard gecko.

6. Poor Diet or Wrong Food Size

Leopard geckos can be picky. If the insects you’re offering are too large, they may feel overwhelmed and refuse to eat. Aim for feeder insects that are no larger than the space between their eyes.

Variety is key, too. Stick with staples like crickets and mealworms, but mix in treats like waxworms occasionally. Make sure the insects are gut-loaded and dusted with calcium. Check out our feeding guide for more ideas.

7. Age-Related Changes

Younger geckos eat more frequently than adults because they’re growing rapidly. As they age, their appetite naturally slows down. Adult leopard geckos might eat only a few times a week, while juveniles need daily feedings.

If your adult gecko is eating less but maintaining a healthy weight, it’s likely just part of their normal routine.

8. Breeding Season Behavior

During breeding season, both males and females can lose interest in food. Males may become preoccupied with finding a mate, while females focus on egg-laying.

For females, provide extra calcium to support egg production. A calcium dish in their enclosure is a good idea, especially during this time. Read more about how to support your gecko with supplements.

When to Seek Help

If your gecko hasn’t eaten for more than a week and is showing other signs of distress (weight loss, lethargy, or visible illness), it’s time to consult a reptile vet. A professional can diagnose underlying issues and provide treatment.

Final Thoughts

Understanding why your leopard gecko stops eating can help you respond appropriately and keep them healthy. Whether it’s shedding, stress, or something more serious, a little observation and care can go a long way.
