The Herp Index: Why Is My Snake Refusing To Eat?

By -

Few things worry snake keepers more than a pet that suddenly stops eating. This causes owners to panic - Why is my snake not eating? Is it stressed? Sick? Or just being a picky serpent?

As a snake owner, I get this question all the time, and the truth is: snakes refusing food can be perfectly normal—or a red flag that needs attention. The trick is knowing the difference.

In this post, we’ll walk through the common reasons snakes go off food, how to separate harmless fasting from health issues, and the practical steps you can take to get them feeding again.

Why is My Snake Not Eating? Common Reasons

Not all feeding refusals are alarming. Here are the most common causes:

    ~ Classic visible signs that Google
    is about to shed ~
    1. Shedding: Appetite often dips a week before shedding. Dull skin and cloudy eyes (“blue eyes”) are tell-tale signs. 
    2. Seasonal cycles: Some snakes naturally slow their feeding in cooler months or during brumation.
    3. Stress: New environment, too much handling, loud noises, or lack of hides can make a snake feel unsafe enough to skip meals.
    4. Wrong environment: Incorrect temperature or humidity is one of the biggest appetite killers.
    5. Meal problems: Prey too large, too cold, or not the species your snake prefers.
    6. Health concerns: Mouth rot, respiratory infections, parasites, or digestive blockages can all show up as loss of appetite.
    7. Reproductive changes: Gravid females may stop eating for a while.

    When to Worry About a Snake Refusing Food

    Refusal during shedding or short seasonal fasts is usually fine. But it’s time to call your vet if you notice:

    • Weight loss along with fasting
    • No food intake for several weeks in young snakes or months in adults
    • Wheezing, nasal discharge, mouth lesions
    • Stuck shed around eyes or body
    • Lethargy or sudden change in behavior

    Here's What You Can Do When Your Snake Won't Eat

    1. Check the Basics

    • Confirm your enclosure has the right temperature gradient (warm basking spot + cooler end).
    • Monitor humidity for the species.
    • Provide secure hides—a nervous snake often won’t eat.

    P.S: look at that crazy iridescent shine on my boy <3

    Vet Tip: A thermometer on the tank wall isn’t enough—use a digital probe at both the warm and cool ends.

    2. Fix the Feeding Setup

    • If possible, provide live prey. Hunting serves as enrichment as well. 
    • Warm thawed prey to approximate body temperature.
    • Try different presentation: tongs, leaving prey overnight, or a slight wiggle to mimic live movement.
    • “Scent” the prey with bedding or fluids from another prey type if your snake is being picky.

    3. Reduce Stress

    • Avoid handling for several days before and after feeding.
    • Place the enclosure in a quiet, low-traffic spot.
    • Stick to consistent day/night cycles.

    4. Time It Right

    • Many snakes are crepuscular or nocturnal—try feeding at dusk or after lights go off.
    • Don’t offer food too soon after a large meal—give digestion time.

    5. Monitor Closely

    • Weigh your snake weekly to track subtle changes.
    • Keep a simple log of feeding attempts, success/failure, and environment.
    • If appetite doesn’t return in a reasonable time for that species—or you spot illness—book a vet visit.

    Real-World Scenarios

    • Corn snake in shed: Refuses food for 10 days, sheds cleanly, resumes eating the next week. Normal.
    • Ball python after relocation: Stops eating, loses weight, found to have low enclosure temps. After heating fixed and hides added, appetite returned. Corrected husbandry.
    • Boa with mouth lesions: Refuses food, drooling noted. Vet diagnosed stomatitis; antibiotics resolved issue. Medical case.

    Closing Thoughts

    A fasting snake isn’t always a sick snake. Sometimes, it’s just nature at work. But as a keeper, your role is to stay observant: check the environment, watch the body condition, and act if red flags appear.

    Patience, proper husbandry, and timely veterinary care go a long way in turning a stubborn feeder back into a healthy, hungry snake.

    ~ A young macaque at the centre ~ When I first came across the announcement for the PfA internship, I wasn’t entirely sure what to expect. The notification spoke of a collaboration between IVSA India and People for Animals (PfA) Bangalore — a week-long internship crafted for some of the most passionate wildlife enthusiasts across the country. A mere seven days didn’t seem like much, but I was intrigued, slightly apprehensive, and undeniably eager to step into something unfamiliar. What I hadn’t anticipated was the sheer depth of experience and learning that would unfold over the course of that single week. Now, as I look back, it’s astonishing how much growth can be packed into just a few days. From reshaping my perspective to sharpening my skills, the journey left an impact far greater than I imagined. Here’s a glimpse into my seven-day whirlwind through one of the most remarkable wildlife-focused NGOs I’ve had the privilege of experiencing. ~ With the team at PfA Bangalore ~ ...

    The Herp Index: Unveiling the Secrets of Reptile Behavior

    By -

    Reptiles are often misunderstood. Cold-blooded, slow-moving, and mysterious, they don’t wear their emotions on their sleeves (or scales) like mammals do. But make no mistake—these creatures have a rich behavioural repertoire. If you’ve ever watched a bearded dragon bob its head, a snake flick its tongue, or a turtle bask under a lamp, you’ve witnessed a complex language of instinct and adaptation. In this edition of The Herp Index , we dive into the fascinating world of reptile behaviour—decoding the why behind the wiggle, the stillness, and the sideways glances of our scaly friends. 1. Tongue Flicking: The Snake's Super Sensor  If you've ever held a snake, you’ve likely seen it flick its tongue rapidly in and out. This isn’t a sign of aggression—quite the opposite. Snakes use their tongues to “taste” chemical particles in the air and transfer them to Jacobson's organ (or vomeronasal organ) in the roof of the mouth. Why it matters: Frequent tongue flicking me...

    The Herp Index: How Do Pythons Eat?

    By -
    Image
    Constrictor snakes — including boas, pythons, and some species of colubrids — are fascinating predators that employ a specialized method of feeding called  constriction . Unlike venomous snakes that inject toxins into their prey , constrictors use brute strength, anatomical precision, and a carefully orchestrated sequence of behaviours to subdue and consume prey . Their feeding process is a remarkable display of evolutionary adaptation involving sensory detection, muscular control, skeletal flexibility, and biochemical efficiency. Let’s dive into the detailed mechanism of how constrictor snakes eat, step by step, including the underlying biology. 1. Sensing and Locating Prey ~ Difference in location of nostrils and heat pits ~ Constrictors rely on a combination of olfaction , vibration sensing , vision , and, in some species, infrared heat detection to locate prey. Olfaction (smell) : The forked tongue collects scent particles and transfers them to the Jacobson’s organ ...

    ~ Handling Remy ~ Several rodent species are heralded as cute animals worldwide. Hamsters, guinea pigs, rabbits, chinchillas, and many more are popular pets that everyone might've seen in several households and social media platforms.  The rodents I find commonly slandered and misrepresented are mice and rats. Usually associated with gutters and trash cans, they're often considered lesser beings or lowlifes and garner little sympathy even from avid animal lovers.  While this does lead to several amusing encounters and reactions with people when they find I have reared and that I find mice and rats endearing, it's high time we clear the air of misconceptions about these critters.  Read on for more about how mice and rats aren't the nasty, offensive creatures people make them out to be and can be just as endearing a pet as your neighbour's hamster.  1.

    Signs of Aggression In Budgies: Behaviors To Look Out For

    By -

    Budgerigars are the cutest, most amicable floofballs around.  They're not usually aggressive towards other birds by nature and will make up quickly after a slight scuffle.  But, under certain temperaments or if put in certain situations, they're also fierce, aggressive birds that given a chance will readily put their neighbour in a tight spot.  Here are some telltale signs of an aggressive bird - Signs of Aggression Typical signs of aggression in budgies and behaviour preceding a fight include -  1.  Lunging and attempting to bite or nip 2.  Screeching and hissing 3.  Flying and trying to land on another bird 4.  Plucking or pulling at another bird's feathers 5.  Chasing 6.  Head bobbing with feather fluffing with pinned irises (when the iris gets very small) Unless you observe two or more of these together repeatedly, keep in mind that these are general signs; your budgie may just be playing with the others.  Pinned irises are ofte...

    Budgerigars, often called budgies, are one of the most popular bird species amongst bird owners. Their friendly personality, adorable character and active persona make them increasingly preferable when picking a pet as a new owner.  However, beneath that mischievous, cute disposition is sometimes a fierce, territorial avian that will not hesitate to dispose of others it dislikes; this can be seen when keeping them with other birds, including budgies.

    This article is in collaboration with IDA Indievets A recent Supreme Court directive has stirred a nationwide debate: all stray dogs in Delhi are to be removed from public spaces and shifted to shelters within the next six months. While the intention—addressing public safety and reducing human-animal conflict—is understandable, the ruling has raised significant concerns among veterinarians, animal welfare experts, and urban planners. Below, we break down what the ruling entails, why implementing it isn’t straightforward, and what a more sustainable approach could look like. The Ruling in Brief On August 11, 2025 , the Supreme Court of India issued a directive to authorities in Delhi and the wider NCR region, ordering the removal of all stray dogs from public areas and relocating them to newly established shelters. The ruling requires: Capturing and housing stray dogs in shelters within eight weeks Ensuring each dog is sterilised, dewormed, immunised , and not rel...

    What Can I Feed My Red-Eared Slider? Foods That My Turtles Love

    By -
    Image
    ~ Turbo trying to finish before the others come ~ Turtles are the literal definition of an introvert, with red-eared sliders being no exception. They also tend to be overly picky about what they’re fed, and as the owner, your pet deems it your job to figure out their moods and what they want to eat.  Furthermore, keeping your turtle on a plain diet of pellets is not the best idea. Thus, to make your life easier, I’ve compiled a list of foods my turtles love to give you an idea of  what you can feed your pet besides regular pellets.  Why aren't pellets enough for  my Red-Eared Slider ? There are several reasons why giving a completely pellet-based diet isn’t the best option for your pet, and this isn’t limited to red-eared sliders.   While the protein proportions may vary with age, turtles are primarily carnivorous and will require animal-based protein in their diet. Giving a wide variety of foods provides enrichment and stimulation and helps maintain nutri...

    7 Reasons You Shouldn’t Get a Conure

    By -
    Image
    Conures are undeniably gorgeous—bright feathers, big personalities, and parrot energy packed into a smaller body. But owning one isn’t all rainbow feathers and Disney moments. From the ear-splitting calls to the decades-long commitment, conures can be a handful—way more than many expect. Here’s why you might want to think twice before inviting one into your life. 1. They’re loud. Painfully loud. Once, I was walking home and heard a very distinct “RIO!”—from an entire lane away. Conures aren’t just “chatty.” They scream . Their calls can cut through walls, neighbours, and your last shred of peace, especially at dawn and dusk. And it’s not just irritating—it can stress them out. When a conure realises loud noises get attention, they’ll double down. Breaking that cycle requires training, boundaries, and sometimes an avian behaviourist… which isn’t exactly beginner-friendly. 2. Not exactly beginner material Yes, they’re smaller than macaws or greys, but they need the same level of ca...
