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.
Show 2 more
  • 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 room for a 3 ft enclosure
  • 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 6 sq ft of floor · 35 x 24 x 18 in

Must be housed alone. Solitary

  • A single adult needs a vivarium of at least 36 x 24 x 18 in, which gives even a big female room to stretch out, and larger is better, 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 basking surface of about 90-95°F and a cool side around 72-75°F via a thermostat-controlled heat source.
  • Keep humidity low to moderate to prevent skin problems, and offer a humid hide during sheds.

Care in depth

Diet

Carnivore - frozen/thawed rodents
  • 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

Signs of good health, and the common problems
  • 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 prolonged feeding-response bite, where the snake holds on and chews, can cause swelling; ease the snake off promptly and seek medical advice if you have an unusual reaction.

Is this urgent?

5 warning signs and how fast to act, 2 of them right away

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. Most snakes have only one working lung, and even boas and pythons, whose second lung is much smaller, have little reserve.
Now
Cannot right itself, or holds the head and neck in an unnatural twist (a western hognose that rolls over and plays dead when disturbed, then recovers once left alone, is showing normal defensive behaviour)Go now. Neurological signs are always urgent in a snake.
Now

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

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.
Check today
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.

Bedding and substrate

2 safe, 2 with a caveat, 4 to avoid

A sandy-soil burrower: the substrate has to be deep and loose enough to dig in, firm enough to hold a burrow, and not chosen to hold humidity.

Safe

Sand-topsoil mixAbout 70% plain, untreated topsoil to 30% play sand (ReptiFiles' mix), at least 3 in deep and 4-5 in for a large adult female.
safe
Aspen shavingsCheap, easy to clean and holds a burrow well, but it does not hold moisture. Replace any patch that gets wet, because aspen moulds when damp.
safe

With a caveat

Paper towel or newspaperReptiFiles lists both among the bad hognose substrates, because a burrower cannot dig in them. Use them for quarantine or mite treatment only, never as the long-term floor.
with a caveat
Cypress mulchChosen to hold humidity for tropical snakes. A hognose is kept at low to moderate humidity and digs in sandy soil, so a soil-sand mix or aspen suits it better.
with a caveat

Never

Coconut fibreReptiFiles lists it among the poor substrates for hognoses.
never
GravelListed by ReptiFiles among the poor choices, and no use to a snake that digs.
never
Pine and cedarThe same aromatic oils that make them unsafe in small-mammal bedding.
never
Uncovered heat mats and unguarded ceramic emittersNot a substrate, but the most common cause of contact burns. Every heat source needs a thermostat, and every emitter needs a guard.
never

Keep humidity low to moderate and the surface dry, with a humid hide during a shed. Clean, dry substrate is what keeps a burrower free of skin and scale infections.

Is your enclosure big enough?

These are the smallest sizes that give good conditions, not legal minimums. More room is always better.

Minimum 6 sq ft of floor · 35 x 24 x 18 in

Every figure, and where it comes from

Sized for the largest females, about 35 in, and above Austria's legal minimum of 5.5 sq ft for one or two adults. Floor space and a deep, loose substrate matter more to a hognose than height.

Minimum floor area6 sq ft of continuous, unbroken floor

CompanyMust be housed alone. Solitary
The recognised standards do not agree on this one
ReptiFiles: 36 x 24 x 18 in, one of its recommended hognose enclosures; 35 x 18 x 16 in (40 US gal) as the minimum for an adult female and 30 x 13 x 13 in (20 US gal) for an adult male; its preferred rule is an enclosure as long as the snake, half its length wide and half its length high. The figure this site uses is that recommended 36 x 24 x 18 in enclosure, written as 35 x 24 x 18 in. ReptiFiles calls its sizes minimums and says bigger is always better. Checked 2026-10-23.
Austrian legal minimum (2. Tierhaltungsverordnung, Anlage 3): 5.5 sq ft of floor and 16 in of height for one or two adults (Heterodon nasicus). A legal minimum, recorded for context. Less than the figure used here. Checked 2026-10-23.

Everyday foods (1)

Frozen-thawed rodentsThe whole diet for these snakes. Choose prey no wider than the snake at its thickest point. Thaw fully in the fridge, then warm in a sealed bag to about 100°F and offer with tongs. One prey item per feed, at the interval in the species guide.
everyday food

That food is not on our list. A snake eats whole prey and nothing else, so if it is not a correctly sized prey item from the species guide, leave it out.

Whole prey is a complete food: snakes fed whole rodents need no supplement dusting.
