Overview

What is this animal?

  • Western hognose snakes are small colubrids named for the upturned, shovel-like snout they use to dig in sandy soil.
  • They are known for a theatrical defensive display, flattening the neck, hissing, and sometimes rolling over to play dead.
  • They are rear-fanged and produce a mild saliva that can cause localised swelling in people but is not considered medically dangerous to most.
  • Their manageable size and quirky behaviour make them popular pets.

Temperament

  • Despite the dramatic bluffing, western hognose snakes are gentle and rarely bite defensively, preferring to hiss and play dead.
  • They are slow, deliberate, and easy to handle once they settle.
  • Food-response bites are more likely than defensive ones, so wash your hands before handling.
  • Their daytime activity and digging make them engaging to watch, and most tolerate handling well.

A good fit for

  • Beginners wanting a small snake
  • Keepers with limited space
  • Those who enjoy quirky behaviour
  • People wanting an active digging species

Common mistakes to avoid

  • Easily overfed and prone to obesity
  • Rear-fanged - bites can cause swelling
  • Some individuals are picky feeders
  • Needs deep substrate for natural burrowing

Enclosure

Minimum 4,050 cm² of floor (628 sq in) · 90 × 45 × 45 cm

Must be housed alone. Solitary

  • A single adult does well in a 90x45x45cm vivarium with a deep, loose substrate that allows burrowing, such as a soil-sand mix or aspen.
  • They spend much of their time buried, so floor space and substrate depth matter more than height.
  • Provide a warm basking area of 30-32C and a cool side around 22-24C via a thermostat-controlled heat source.
  • Keep humidity low to moderate to prevent skin problems, and offer a humid hide during sheds.

Diet

  • Wild hognose snakes favour amphibians, but captives usually take appropriately sized frozen-thawed rodents.
  • Choose prey about as wide as the snake and feed juveniles every 5-7 days and adults weekly to fortnightly.
  • Females grow much larger than males and need bigger meals.
  • Some individuals are fussy and may need prey scented with toad or fish to start feeding.
  • Avoid overfeeding, as hognose snakes gain weight easily.

Health

  • Hognose snakes are hardy but prone to obesity from overfeeding, and to respiratory infections if kept too humid or cold.
  • Because they burrow, clean, dry substrate is essential to avoid skin and scale infections.
  • Watch for retained sheds and provide a humid hide during shedding.
  • Quarantine and mite-check new animals.
  • The mild venom means a defensive bite can cause swelling, so seek medical advice if you have an unusual reaction.

Is this urgent?

Most snake worry is about feeding, and most feeding worry is misplaced. Check the guide for this species' normal fast before treating a refusal as illness.

Go now

Open-mouth breathing, bubbles at the nostrils, or an audible whistleGo now. Respiratory infection. Snakes have one functional lung and little reserve.

Cannot right itself, or holds the head and neck in an unnatural twistGo now. Neurological signs are always urgent in a snake.

Today

A regurgitated mealDo not offer food again for at least a fortnight. Check the warm-end temperature today, then call if it happens twice. Usually too cold, handled too soon, or a meal too large. Repeated regurgitation is a different and more serious problem.
Today
Retained eyecaps after a shed, or a ring of stuck shed on the tail tipRaise humidity and provide a damp hide. Call if it is not resolved within a day. Almost always humidity that was too low during the blue phase. A constricting ring costs the tail tip.
Today

Soon

Refusing food for longer than is normal for this speciesLog the refusal and check the species guide. For an adult ball python, a fast of about a month is not in itself a cause for concern, and much longer voluntary fasts are documented. Weigh weekly through it. The weight trend, not the calendar, is what tells you whether a fast matters.
Log it first

This is general guidance for a healthy adult, not a diagnosis. An exotics vet who knows your animal always overrides it — and the time to find one is before you need one.

Can a western hognose snake eat that?

Reptile diets split hard by species. An insectivore and a grazing tortoise share almost nothing, so check the species guide as well as this list.

The full list

Never (15)

AlcoholNo safe amount at any body weight on this site.
never
AvocadoPersin. Fatal to many reptiles.

CitrusToo acidic, and it interferes with calcium absorption.
never
Dog or cat foodProtein and vitamin D levels formulated for a mammal. In tortoises it causes irreversible kidney and shell damage.

Iceberg lettuceWater with no nutrition. It fills a reptile up in place of food that would have done something.

Rare treats (1)

WaxwormsVery fatty. Useful for a underweight animal or for medicating, addictive otherwise. One or two, rarely.
rare treat

Occasional (5)

Bell pepperSafe, low oxalate, and the colour gets a refuser eating. A few small pieces a few times a week.
occasional
Butternut squashWell tolerated and a useful source of vitamin A precursors. Small cubes a few times a week.
occasional
KaleGood calcium, mild goitrogen. Rotate it. Twice a week.
occasional
MealwormsHard chitin shell and a poor calcium ratio. Fine as part of a varied feed, poor as the whole diet. A few, alongside better feeders.
occasional
SpinachOxalates bind dietary calcium, which is the last thing a reptile at risk of metabolic bone disease needs. A very small amount, rarely.
occasional

Everyday foods (6)

Black soldier fly larvaeUnusually high in calcium; one of the few feeders that does not need dusting. Several per feed.
everyday food
Collard greensOne of the best staple greens for herbivorous and omnivorous reptiles. Daily.
everyday food
CricketsA standard feeder. Gut-load them for 24 hours before offering, or you are feeding an empty shell. Sized no wider than the space between the animal's eyes.
everyday food
Dandelion greensExcellent calcium-to-phosphorus ratio and readily taken. Pick away from sprayed ground. Daily, for herbivorous species.
everyday food
Dubia roachesBetter calcium ratio and more meat per insect than crickets, and they cannot climb glass. Sized to the animal.
everyday food
Mustard greensGood calcium ratio; rotate with other greens. Several times a week.
everyday food

That food is not on our list. Reptile diets are narrower than they look — check the species guide, and ask an exotics vet before offering anything unfamiliar.

Dust feeders with a calcium supplement to the schedule in the species guide. A reptile can be eating well and still be starving of calcium.

What it really costs

Setup, monthly, first year and across a whole life, itemised and with the electricity worked out from the actual wattage. Published figures for the same animal disagree by a factor of four, so the calculator shows ranges rather than picking one.

Bedding and substrate

For snakes the substrate has to hold the right humidity for the shed, and let the animal get fully under it.

Safe

Cypress mulchHolds humidity without going sour quickly. A common default for tropical snakes.
safe
Aspen shavingsThe classic for colubrids. Excellent for burrowing; replace any patch that gets wet.
safe
Topsoil and coco fibre mixBioactive-ready and holds a burrow.
safe
Paper towel or newspaperQuarantine, feeding response problems, and post-surgery.
safe

With a caveat

Aspen in a high-humidity setupIt moulds. Aspen suits dry-side species; wet species need mulch or soil.
with a caveat

Never

Pine and cedarAromatic phenols.
never
Sand for species that are not desert animalsAbrasive and dries the skin, causing shed problems.
never

Stuck shed and retained eyecaps are usually a humidity failure during the blue phase, not a substrate failure afterwards.
