Burmese Python (Python molurus bivittatus)

 

Burmese Pythons, because of their docile nature and undemanding requirements, are among the most suitable of the large snakes as captive animals. It's been more than 35 years since I got my first Burmese, and the species still remains my favorite.

 

There's no denying the popularity of the Burmese python. And as long as you're sure you have the space to properly house one, you, too, should be able to discover why I still like them so much, after all these years.

 

Burmese Python Availability :

 

Burmese pythons are readily available in a variety of colors and patterns, with new traits and trait combinations becoming available with increasing frequency.

 

Burmese Python Size :

 

Burmese pythons are among the largest snakes and can potentially reach lengths of more than 20 feet and weights in excess of 250 pounds. Snakes of this size, however, are unusual and do not reach these proportions quickly or by accident. Growth is rapid initially, but slows considerably after about 10 feet. The average adult Burmese in captivity is probably about 11 or 12 feet long.

 

Burmese Python Caging :

 

Most importantly, the cage should safely contain the snake. After all, subsequent requirements are less important once the snake has disappeared into that hole in the wall behind the washing machine because you forgot to properly secure it.

 

The size of the enclosure should be large enough to allow the snake a reasonable amount of movement, yet small enough to permit accurate temperature and humidity control. Burmese pythons are terrestrial snakes that spend most of their time on the ground, so the floor space of their enclosure will be more important to the animal than the height of the cage.

 

A baby Burmese will require the space equivalent of a 10-gallon aquarium. Larger individuals will need more space, of course. A 200-pound animal will need floor space measuring at least 4 feet by 8 feet. I recommend the enclosure have roughly the floor space equal to four to six times the area of the snake itself when it's in a flat coil. The cage should also have a door that allows easy access and that can be closed securely. A glass or Plexiglas window for viewing is important, as well. Some ventilation is desirable, although not as much as one might initially think. Heat and humidity are easily lost through vents, especially through those on the top of the enclosure. Small vents located on the sides of the cage will permit adequate air exchange.

 

Wood, plastic and glass are all acceptable materials for cage construction. I use enclosures that are constructed of ABS plastic, and which have a smooth, nonporous finish that allows easy cleaning and sterilization. All corners and edges are rounded, leaving no difficult-to-clean areas. The cages are lightweight, have large tempered glass viewing areas and, best of all, someone else has made them already.

 

Burmese Python Substrate

 

There are several decent cage substrates available. It is virtually impossible to provide a naturalistic vivarium for a large python, unless only the sturdiest of materials are used. Substrates are generally selected for utility rather than aesthetics. Newspaper is absorbent, fairly sterile and readily available. Various woods, shavings and shredded products are acceptable, too, although they tend to foul in moist environments.

 

Burmese Python Lighting and Temperature

 

Burmese pythons prefer temperatures in the mid-80s Fahrenheit. Slightly cooler temperatures are allowable at night. Indeed, cooler night temperatures are essential to breeding Burmese pythons, should you desire to eventually undertake this endeavor.

 

Because Burmese pythons require temperatures above what we consider comfortable in our homes, it is necessary to raise the temperature of the enclosure with a supplemental heat source. This heat can be provided in several ways. I prefer to use a heat pad or heat tape underneath the enclosure. Heat pads or undertank heaters are available in many pet shops that stock reptile supplies. They provide safe, even heating for smaller enclosures. Heat tape is also available and serves the same purpose, although it allows more flexibility in heating larger areas more economically. Various types of heat bulbs are readily available and are effective, as well.

 

It is important, though, to give the snake some choice in determining its own temperature. In the wild, the animal would be able to thermoregulate by freely moving between warmer or cooler areas. These choices are limited in captivity, but by proper heater placement, it is possible to give the snake some control over its own temperature. The maximum thermal gradient can be obtained by placing the heater at one end of the enclosure rather than in the center. It will be warmer nearer the heater and cooler as the distance from the heater increases. This will give the snake a wider range of choices in regulating its own temperature.

 

The heater, it should be noted, serves two purposes. It provides a warm area so the snake can increase its body temperature, yet it also provides the heat that increases the ambient temperature of the enclosure. Depending on the type, size and construction of the cage, heat loss from the cage and the temperature of the air outside the cage, the heater may need to be much warmer than the average temperature of the enclosure itself. This is cause for alarm for many novices. It is perfectly acceptable to have a temperature of 100 degrees Fahrenheit or more directly over (or under) the heat source if this is necessary to maintain the desired ambient temperature. Always be certain, however, that the snake can retreat to a cooler area as it sees fit.

 

The temperature of the enclosure can be regulated in several ways. In the first and most primitive way, the temperature can be controlled by initially selecting a heater with an output that provides the acceptable amount of heat. If ambient conditions outside the enclosure are constant and the heater output remains the same, then the temperature inside the cage should remain constant, as well. It is difficult to select a heater with exactly the heat output necessary, and constant conditions outside the cage are not always as constant as they might be. A rheostat or dimmer switch can adjust the heat output of a heater by adjusting the power input, the other problem can be overcome by using a controller with a feedback system.

 

Because a thermostat monitors the temperature of the enclosure and activates the heater to add heat when appropriate, it is by far the best method for controlling cage temperature. There are two types of thermostats on the market for use in herp-related applications. The conventional on/off type operates like the thermostat in your house; it senses when the temperature has dropped below a certain level and directs the heater to add heat until the set temperature is reached. A proportional thermostat is much like a rheostat with a feedback system. The thermostat continuously monitors the temperature and makes slight adjustments in the electrical current to the heater. In this type, the heat is always on, but only at the level necessary to maintain the set temperature. Proportional thermostats eliminate the fluctuations caused by the on/off cycle of conventional-type thermostats and provide a continuous warmth from the heat source. I recommend (and sell, wouldn't you know) the Biostat line of thermostats. Wild Burmese pythons live in areas of high humidity, and captive animals require the same. Adding heat to the enclosure can dry it out and provisions must be made to retain moisture. A tightly constructed cage with a water bowl and minimal air vents should keep the relative humidity above 60 percent or so. Wooden cages should be painted and sealed.

 

Aquariums with screen tops are difficult to regulate. Heat rises and escapes through the top, requiring additional heat to maintain the appropriate temperature, which further dries out the enclosure. Aquariums should be used with tops that restrict heat and moisture loss.
