Ball Python Care

The Ball Python or Royal Python, Python regius, is a wonderful pet snake species, as they are generally very gentle and docile animals.

When they feel threatened, the snake will coil into a tight ball hiding its head which is where the name “Ball Python” comes from. They are relatively long-lived and may easily surpass 20-30 years of age with proper care, so one must be prepared to take care of their pet for several decades. Like with all reptiles, good husbandry and preventative health care are important for a long and healthy life.

Ball Pythons are native to central and western Africa, naturally found in grasslands, savannah, and the borders of wooded habitats. They are nocturnal (active predominantly at night), commonly found taking shelter in termite mounds and mammal burrows during the day. They are a heavy-bodied snake averaging a body length of 1.0-1.7 m (3-5 feet) with females typically being longer and heavier than males.

In the past, Ball Pythons were commonly wild caught and made poor captives, as the stress from capture and transport, and their inability to adapt to captivity lead to many health problems. Today the vast majority of Ball Pythons in the pet trade are captive bred and are well-adapted to life as companion animals. There are many colour and pattern variations that have been selectively bred for.

Environment: Enclosure

There are many suitable reptile terrariums available on the market today. Most are made of glass with screen paneling for ventilation, but an aquarium with a securely-fastened screen lid is also a suitable enclosure. While these snakes are primarily terrestrial (live on the ground), in the wild they are often found climbing in trees and offering climbing opportunities in captivity helps to maintain a healthy snake.

Ball Pythons, like most reptiles, do best when housed alone because of their solitary nature. The minimum floor space required for one adult python is about 2700 cm2 (432 in2), or the floor space in an average 114 L (30 gallon) aquarium.

Environment: Heating

Reptiles are ectothermic: They rely on external heat to maintain their bodies at a preferred temperature. All reptiles need an external heat source so that they may thermoregulate by shuttling within a heat gradient in their enclosure. Basically, when a reptile is too cool he will move to somewhere warm, and when he is too warm he will move somewhere cooler. Reptiles will move around in the gradient throughout the day to try to stay at a target body temperature.

To create a thermal gradient in the enclosure, a primary heating device should be placed on one end. In some homes, a secondary heating device may be necessary to maintain temperatures warm enough. The primary heating device can be a heat lamp left on during the day. Heating pads make excellent secondary heating devices if needed at night. Ceramic heat emitters and radiant heat panels may also be used for nighttime heating as they do not produce light. Red coloured incandescent bulbs, sometimes called “infrared” bulbs, should not be used for nighttime heat as reptiles certainly see the red light, contrary to what they often advertise.

The preferred optimum temperature zone for Ball Pythons is 25-35 ⁰C (77-95 ⁰F) during the day, and no cooler than 20 ⁰C (68 ⁰F) at night and the cage environment should reflect this. Two thermometres are required for monitoring temperatures: One to monitor the warm end of the gradient to ensure that it is warm enough, and one to ensure that the cool end is cool enough to allow for thermoregulation.

Monitoring the thermal gradient is critical: Use a thermometre both at the animal’s basking spot as well as at the cool end of the enclosure. It is not only important to ensure that your pet can get warm enough based on the species’ preferred body temperature, but also that the cool end allows for proper cooling when needed. Hyperthermia, or an excessively high body temperature, can kill a reptile or amphibian within minutes, and ensuring that your thermal gradient is appropriate at both ends is critical. We recommend the usage of either a digital thermometre with a probe that may be placed at the appropriate spot, or a noncontact infrared temperature “gun” that can be pointed at any location in the enclosure. Note that some thermometres are not very accurate and may be misleading when monitoring temperatures. “Stick-on” LCD and dial thermometres are generally quite inaccurate and we do not recommend their use.

Environment: Lighting

In the past decade, there is more and more research indicating that snakes can benefit from broad-spectrum lighting. While in the past it has been demonstrated that rodent-eating snakes can be raised and bred without lighting that offers UV-A or UV-A radiation, new research has demonstrated that they can benefit from it. We recommend broad-spectrum lighting with all reptiles; please refer to our handout on lighting for reptiles for more information.

Reptiles require a regular photoperiod (“daylight” period) in captivity. Twelve hours of daylight to 12 hours of darkness is often accepted. Please use an electric timer to keep the photoperiod regular for your snake.

Environment: Substrate and Cage Furnishings

Substrate is the medium covering the floor of the enclosure. For newly acquired snakes, we strongly recommend using an easy-to-clean material like unprinted newspaper or paper towels so that the animal’s stools and urates can be monitored (and a sample easily collected for parasite screening).

Once the animal is given a clean bill of health, the substrate can mimic what is found in their natural habitat to allow for some burrowing and a moisture gradient in the enclosure. A mix of wood chips, moss, sand, and soil creates a forest floor-like substrate.

Wood shavings such as aspen are easy-to-clean and allow for burrowing, but do not allow for a moisture gradient to be created in the substrate. If you are using wood shavings, please be sure to provide one or more humid hides (see below) so that the snake has a humid retreat. Please note that aromatic woods like cedar and pine produce fumes that are toxic and these woods should never be used.

These animals need hiding spots so that they may hide to feel secure. There are many commercially-available caves and other hides made out of resin that are easy to clean and disinfect, but simple hides can be made out of plastic food containers or plant saucers. Hiding spots should be just large enough for the snake to enter and coil up snugly, as larger hides do not offer the same sense of security.

A moist or humid hide is essential so that the snake can retreat to a refuge with higher humidity, important for hydration and shedding. If you are using a naturalistic forest floor-like substrate mix, the substrate under or inside one or more hides can be dampened regularly to create a moisture gradient. If you are using a dry substrate like aspen shavings that do not allow for a moisture gradient, you can use any hide filled with moist paper towels or sphagnum moss to allow for a humid retreat. Any humid hide should be cleaned and moist substrate changed regularly to avoid mold growth.

The minimum number of hides is three: One “dry” hide in both the warm and cool ends of the enclosure, and at least one humid hide. This allows the snake to hide in both ends of the gradient for thermoregulation. Other cage furnishings such as rocks, branches, and fake plants add behavioural enrichment and aesthetic value to the enclosure. Ball pythons will climb branches if given the opportunity, and this is a great way to provide exercise.


Ball Pythons are carnivores, and eat many different prey species in the wild, but mostly rodents. As companion animals, they may be maintained on a diet of rodents such as suitably-sized mice or rats. Rodentivores are a subset of carnivores that specialize in eating rodents.

1. Selecting healthy prey
Healthy prey leads to a healthy predator! Rodents that are fed to your reptile should be healthy. Their fur should be clean, they should not have a foul odour, and their eyes and ears should be clear of any discharge. Rodents should be of a good body condition score. Feeding underweight or malnourished rodents may lead to nutritional deficiencies in your reptile, just as feeding overweight or obese prey will lead to an obese predator and other nutritional deficiencies. Supplementation with calcium or multivitamins is not necessary as long as the prey is healthy, with the exception of feeding neonatal (“pinkie”) mice and rats. “Pinkies” are naturally lower in calcium, so a calcium supplement is necessary on these meals to ensure that no deficiency in calcium occurs. It is a commonly propagated myth that pinkies that have just nursed are higher in calcium (and as such, have a stomach full of milk which is visible through their translucent skin): This is not true, they still require calcium supplementation.

2. Safety practices
Rodents should be offered during the reptile’s activity period, so nocturnal snakes should be fed at night, and diurnal snakes should be fed during the day. This is to avoid leaving a deceased rodent spoil in the cage, which is unsanitary and if eaten may cause some digestive upset.

Always wash your hands thoroughly after handling rodents. Snakes sometimes get excited about the scent of prey and will bite a human hand that smells like prey before waiting to see if it is actually a meal. Rodents that are being offered to a snake should always be held in a tool such as tongs, forceps, or hemostats to avoid biting accidents.

We strongly recommend feeding your snake outside of the enclosure, in a separate feeding bin. This can be a plastic storage container with a tight-fitting or locking lid. The snake may be placed in the food container, and the rodent then offered with a pair of tongs, forceps, or hemostats. The snake is then allowed to eat its prey, and can be moved back to its enclosure after it has finished. There are a number of reasons why this feeding method is advantageous:

  • The snake will not learn the association that the enclosure opening means that food is coming: A common complaint among people who keep snakes is that they are attacked as soon as the enclosure is opened. Often, this is a habit formed by feeding the snake in the enclosure—snakes will quickly learn where food comes from, and if they’re hungry, they may not wait to see if it is your hand or a rodent coming into the enclosure.
  • Accidental ingestion of substrate is avoided: If you are using a “loose” or particulate substrate (sand, moss, wood shavings, etc.), pieces of substrate may get stuck to the rodent and be eaten accidentally. Problems such as gastrointestinal impaction, gastrointestinal perforation, or even stomatitis (oral infection) can occur from pieces of substrate getting stuck in the wrong place.
  • Nervous or shy snakes that do not eat in the enclosure may be more inclined to eat when confined to a feeding container with their prey. The reason for this is not known, although a common theory is that this simulates the snake entering a rodent burrow, where their meal can be found.

Frozen rodents should be stored in an airtight container, such as a zipper lock freezer bag, and for no more than 3-6 months to preserve freshness. Some snakes will not accept rodents that have been “freezer-burned.”

The safest method for thawing frozen rodents is to leave them in the fridge overnight, as this has been demonstrated to reduce bacterial growth. Prior to feeding, soak the rodent in a warm-water bath to make the prey more appealing (many snake species rely on detecting body heat as well as the smell of the prey to identify it). Please ensure that the water is comfortable to the touch and not hot enough to burn, as this may cause serious burns in the oral cavity and esophagus of the snake.

Prey that is uneaten is ideally discarded and should not be “recycled,” either by giving it to another animal in the home (this can contribute to parasite transmission between enclosures), or by re-freezing it (to reduce the chance of the meal spoiling).

3. Live or pre-killed?
This is a popular debate among reptile-keepers: Do you feed live prey that provides a “hunting” experience, or pre-killed prey? In truth, pre-killed prey is much safer, and it does not deny the reptile environmental enrichment contrary to popular belief. While nobody is pre-killing prey for wild snakes, these animals are in our care and not in the wild. Like with all aspects of caring for pet reptiles, we want to reduce incidence of health problems and allow them to live long, healthy lives.

In the wild (and in captivity), snakes are predominantly ambush predators: As they lack arms and legs, they rely on stealthy camouflage and the element of surprise when stalking prey. Placing a live, fearful rodent into a small and restricted enclosure may result in serious injury. Rodents can be quite vicious when defending themselves, and a hyperactive, frightened mouse or rat bouncing around a reptile enclosure may actually scare a snake into not wanting to eat.

Rodents are capable of causing serious damage to a snake that does not want to eat, whatever the reason for inappetence may be. Rodents tend to gnaw along the head and back of snakes, and damage to eyes and the spine are not uncommon. Bites to the spine may commonly develop meningitis. When a snake is attacked by a predator (or its prey-turned-predator), their first defense is often to freeze and hope that whatever is attacking them leaves them alone. Snakes prefer to flee rather than fight, and if there is no opportunity to get away from the attacking rodent then the consequences are often serious. If you choose to feed live prey to your snake, never leave the live rodent unattended with your pet snake to help avoid these complications.

Another concern is that allowing the rodent to be “stalked” in a restricted enclosure by a predator can be considered inhumane. As reptile-keepers often do not have public opinion on their side, this is an important aspect to consider for the public image of the hobby. Feeding humanely euthanized rodents is more ethical than allowing a frightened animal to be stalked and slowly killed by its predator.

4. Transitioning to pre-killed prey
Most snakes that are eating live prey can be transitioned easily to pre-killed prey. There are a number of steps to try:

  • Often, using a feeding container alone will convince snakes to eat pre-killed prey.
  • Ensure that the pre-killed rodent has been warmed. Soaking the rodent in a warm-water bath is very effective, but ensure that the water is comfortable to the touch and not hot enough to burn (this may cause serious burns in the oral cavity and esophagus of the snake).
  • Offering the rodent on tongs and “jiggling” it will often attract a snake’s attention. Hold the rodent around the hips and not the tail to give it a more natural movement.
  • Making a small tear in the rodent’s skin to expose blood or organs can stimulate some snakes into feeding.

We do not recommend “force-feeding” rodents to snakes or restricting access to water to stimulate feeding without veterinary supervision. While these techniques are commonly recommended on the Internet, in an anorectic snake serious complications such as skin tears and dehydration can occur.

Fresh water should be available in a dish at all times.


Good husbandry helps prevent most health problems in reptiles. As ectotherms, their immune system function is directly affected by both stress and their ability to thermoregulate, so proper environmental temperatures are critical. There are some other common health problems that you can avoid with the right precautions.

Parasites are unfortunately very common in captive reptiles due to overcrowded, stressful conditions and poor hygiene in pet stores and some breeding operations. Many parasites that affect Ball Pythons have a direct life cycle, meaning that they require no other species to help transmit them. Parasites like this tend to accumulate in captive reptiles and cause disease. Fecal testing is required to determine what kind of parasites your snake may have so that the appropriate medication can be prescribed.

Contrary to popular belief, captive-bred rodents are not a common source of parasites in snakes. While rodents have their own species of parasites (such as the rat pinworm, Syphacia muris) that will sometimes be found on snake fecal exams, these act as “pseudoparasites” since the rodent parasite does not mature in or infect the snake. It is important to have fecal exams performed by a qualified veterinary team that can identify pseudoparasites, so that you do not treat a snake for no reason!

Obesity is common in captive Ball Pythons that are overfed, under-exercised, or both. Because these snakes are naturally heavy-bodied, many owners do not realize that their snake is overweight. Like in other species, obesity is not a harmless condition: It predisposes an animal to liver disease, arthritis, and even some cancers. Please consult with our staff if you are concerned that your snake could be overweight.

Let’s get Active!

I am sure you all know that it's important to make sure our furry friends stay active. However, once winter time hits well that is simply more difficult with the snow and storms that come around. So then how do we keep our friends active in winter as we would in spring/summer? Why is physical activity & mental stimulation so important for animals? Well simply put, as humans do, if they are stuck inside, they will get bored which then can make them become destructive and have other negative behaviors. Cats Cats may not always be outside walking like dogs, but you may still notice with the change in weather maybe they are slowing down and not exercising like they should? Here are some helpful ways to encourage them to exercise. Set up a game of hide and seek and hide toys or treats for them to find. Bring in something new from outside like a stick to mentally stimulate them and work out their brain. The new smells and textures can be very enriching for them. Winter is the perfect time for box forts for our kitty friends. If you have spare time made them a kitty castle or kitty boat whatever your imagination can think of! And of course, everyone likes a little stimulation from Tv. Put on something on the tv or a tablet and let them watch it but be careful they do not knock over your TV. Dogs Our dog friends love to be outside! This is great when the weather is cooperating but on those days that it just makes no sense to go outside or is unsafe to so you can try these helpful exercising tips. Let them walk/run on a treadmill. Now as great as this is for exercise you also need to be careful. Desensitize them to the treadmill first, and start slowly. It can be dangerous if not done properly. If your furry friend likes car rides, go on a trip together even just a short one. Let them enjoy the different sights and smells. Winter is perfect time to learn new tricks! This is the time to teach them that special trick you have wanted to for a while. Set up an obstacle course in your house for them to try and get through.
