How big can ball pythons get? (Size chart included) - Animal Nerd (2023)

Ball pythons are among the most popular reptiles in the world, and with good reason.

ball pythons are coming6500 different varieties.

There are pastel ball pythons, albino ball pythons, purple pythons, black pythons, red, yellow, and striped ball pythons, clown, bumblebee, and spider designs to name a few.

Even in the wild, some ball pythons were so beautifully colored that African kings wore them as ornaments, prompting 19th-century zoologist Shaw to give them their scientific name:King of Pythonor "royal python".


How big can ball pythons get?

Ball pythons can be very sociable. No snake is clingy, but ball pythons are naturally easy to train and obedient.

And ball pythons are very easy to manage.

They are the smallest of all African pythons.

Adult males can be up to 79 cm long. Females grow to about 102 cm.

Some well-fed ball pythons kept as pets reach 6 feet (183 cm) in length.

You don't have to worry about your python getting too big to handle it.

But ball pythons are notoriously picky eaters. The challenge in keeping a ball python healthy isn't keeping it from overgrowing, it's making sure it grows big enough.

In this article, we tell you everything you need to know to help your ball python grow and maintain a normal weight, and what you can do if your ball python is anorexic.

Ball pythons are born eating

Ball pythons usually get their first meal two weeks after birth, right after their first moult. But ball pythons are born with food. Where do you get your first meal from?

About 24 to 36 hours before the egg python hatches, it breaks through cracks in the eggshell with its egg tooth.

The unborn snake absorbs nutrients from the egg yolk through the blood vessels in its "navel", the navel.

When the baby ball python ingests the yolk, the umbilical veins fall off and the python breaks out of its shell.

In the wild, baby pythons face extreme danger from predators, sometimes including another hungry adult python!

However, ball pythons kept as pets are separated, housed in separate rooms, and given their first meal.

Your ball python's first meal imprints its idea of ​​food on your pet

Most ball pythons in the wild do not survive long after hatching.

They are attacked and eaten by birds, wild dogs and hyenas, large frogs, large insects, and large spiders.

The female lays 3 to 16 eggs and only 1 or 2 chicks survive the first year.

We don't really know if some wild baby pythons are starving because they're picky eaters.

But we do know that captive ball pythons can decide that the first prey they're ever given becomes "food."

It's important to be able to feed your ball python regularly as a first step.

If your ball python gets a rat or a mouse as its first meal, it knows rodents are food. For example, if he gets an exotic tree frog, he will indefinitely expect a tree frog for his second, third, and future meals.

Never feed a ball python live rodents. Live rodents can fight! They can also bite you if you put them in a cage where your ball python can feed.

Only feed your ball to previously killed rodents. They are available frozen from pet stores. You slowly thaw them to room temperature and then feed them to your ball python using metal tongs. You use tongs because your fingers are edible too!

Don't microwave rodents for your python. Defrosting in the microwave may make part of the rodent too hot to eat.

Microwaves can destroy the enzymes and vitamins the ball python needs to stay healthy. And if possible, feed python rats instead of mice.

Baby ball pythons gain weight faster when fed rats rather than mice

Rats provide ball pythons with more nutrients than mice. Frozen rats and frozen mice have about the same mineral and vitamin content, but mice have more fat and rats have more protein.

Feeding python rats instead of mice will make them bigger and stronger, but not so big that they're difficult to handle.

Ball pythons typically weigh 70 to 72 grams when they hatch.

If a ball python feeds a small mouse as its first meal, it will weigh between 76 and 78 grams at one month of age. If fed to an immature rat, it will weigh between 98 and 100 grams at one month of age.

If you continue to feed baby ball python mice once a week, they will weigh 115 to 120 grams by two months of age. If you continue to feed your young ball python rats once a week, they will weigh 125 to 130 grams by two months.

At three months of age, mouse-fed pythons weigh 150 to 165 grams. Ball python-fed rats weigh between 180 and 200 grams.

Mouse-fed ball pythons are catching up, weighing between 180 and 200 grams by four months of age. But at this point, rat-fed ball pythons weigh between 270 and 280 grams.

Mouse-fed ball pythons still weigh 60 to 80 grams less than rat-fed ball pythons.At 12 months of age, mouse-fed pythons weigh 480 to 500 grams, while rat-fed pythons weigh 540 to 550 grams.

Both ball pythons still only weigh about a pound. But a rat-fed ball python is bigger and stronger, and if it's a female, it'll reach egg-laying age earlier.

Whether you're feeding python rats or mice, you need to properly size snake prey.

Ball pythons can relax (not really unnerve) their jaws to swallow a nice specimen up to 1.25 times the width of their mouth.

Preventing and treating obesity in your ball python

Obesity is a worryingly common problem in all python species, including ball pythons. Obesity is caused by a combination of different factors.

Ball pythons generally don't get much exercise, especially if they aren't tame enough to be taken out of the enclosure.

Most ball python owners feed their snakes pre-frozen and thawed mice, which have a higher fat content than rats and reptiles.

If you feed a ball python mouse that gains weight at the same rate as when you feed it to rats (see the section above), it probably isn't growing fast. I guess it's obesity.

Signs of obesity are wrinkled scales. Sometimes obesity causes the scales to wrinkle. The visible space between the scales is created by excess subcutaneous fat.

The skin of an obese python is very soft to the touch. Its body will be round and not flattened at the top or bottom.

If your ball python is less than a year old, weigh it once a month to make sure it is growing normally. If his weight is higher than expected, check for signs of obesity.

Male ball pythons should stop gaining weight by the age of 16 to 18 months.

Females stop gaining weight by the age of 27 to 31 months, except when laying a clutch.

Mature males and females who are not laying eggs should not gain weight at monthly weighing.

If they are gaining weight as described above and are showing signs of obesity, they should be fed less.

How much you should feed your ball python depends on its age:

  • Ball python chicks need food every 5 to 7 days.
  • After a year, ball pythons need food every 7 to 14 days to be fully grown. They rarely need more food.
  • Adult ball pythons only need feeding every 14 to 42 days, but may require multiple rodents to feed.

Overweight ball pythons need to be fed rats instead of mice. Most ball pythons will have no problem with the switch. However, anorexic ball pythons present a different challenge.

What to do if your ball python is anorexic

Weighing your snake is the best way to ensure it is eating enough.

If an immature ball python isn't gaining weight or an adult ball python is losing weight, anorexia can be a problem.

Getting a python to eat requires different strategies at different stages of its life.

Young ball pythons less than a year old may be reluctant to slap, wrap and swallow food.

Placing a small live rodent in a ball python enclosure will encourage it to defend itself by attacking.

Then he realizes that the rodent you put in the box is food. It is always better to feed your ball python previously killed, previously frozen food, but sometimes live food is necessary to elicit an appropriate response.

In their natural habit, ball pythons stop feeding when night-time temperatures in the tropics are relatively low, as low as 21 °C (70 °F).

An increase in the temperature in the hose housing by 3 to 5 degrees Celsius stimulates the snake's appetite.

Days and nights always last about 12 hours in the tropics. Giving your ball python 12 hours of light and 12 hours of darkness can also stimulate their appetite.

The next thing to try when a ball python isn't eating is to diversify its diet.

Give him a newly weaned gerbil, a thawed adult gerbil that has been previously killed and frozen, or another rodent.

Offer him a mouse if you fed him rats, or a rat if you fed him mice.

The Brown Bag Method

If these steps don't get your snake to eat, try the brown bag method. Increase the temperature in the ball python housing to 85°F to 90°F (29.4°C to 32.2°C).

Punch a few holes in a brown paper bag. Place your python in a pouch with a live, almost weaned rat. Since the rat is alive, it triggers a shock reaction. Since he has just been weaned, he cannot physically harm your snake.

Fold the top of the bag with the snake and rat inside. Then close with staples. Leave the ball python and rat bag in the snake terrarium overnight.

If your snake eats a rat, the problem is solved. If not, try again a week later with another pet. Repeat this until your snake decides to eat.

rodent hole method

Cut a hole in the side of the plastic bucket large enough for the hose to fit through.

Then place the newly weaned rodent, part of its bedding and some feces or urine in a bucket and cover with a lid.

Lower the bucket into the snake hutch and leave it overnight.

This method encourages shy snakes to overpower and eat weak animals.

If your snake doesn't eat when you first put a rodent in the hole, put another rodent in the same bucket once a week until it decides it's time to eat.

Grass and Leaf Method

Replace the substrate on the underside of the ball python's enclosure with dry hay grass to simulate your snake's natural environment.

Drop the young, newly weaned rodent onto the dry grass and close the snake cage lid. If your snake doesn't eat the rodent, take it out and try another rodent next week.

Feeding live ball python prey is not ideal. Your goal should be to get the snake to eat a previously killed victim if possible.

Adult rats and gerbils have been known to severely injure and even kill ball pythons.

It is also inhumane to leave a living victim waiting in the enclosure for more than 30 minutes to be eaten. You must always supervise your snake when feeding it live prey.

As a last resort, your vet may force-feed the snake.

If you are not trained in this procedure, you should leave it to your veterinarian. Anything that makes your snake vomit negates the benefits of force-feeding.
