Californian kingsnakes are the most commonly seen and bred of the kingsnake family in captivity. They are now available in a number of colour and pattern mutations, and have even been hybridized with many other species. They are a reptile eating species and are voracious feeders, but commonly take rodents in captivity. They are very hardy and can be expected to live for approximately 15 – 20 years, making them an excellent choice for a pet snake.
Housing
When keeping any snake as a pet, you generally want to be able to view the snake from the outside of its enclosure, in the most natural surroundings you can offer. This will be more aesthetically pleasing and also aid in the general condition of the snake. If the snake likes its surroundings, it will have a better feeding response and generally grow quicker. A larger vivarium also offers more interest to the snake's life, and by adding branches and other natural products you will enhance the quality of life the snake has, and stop it from becoming lethargic and overweight. Also, being stronger it should have more of a resistance to any viral infections or any other problems that it may encounter later in life.
For an adult kingsnake a vivarium 120cm Length x 45cm Width x 45cm Height is ample. Contrary to popular belief, and propaganda spread by various campaigners, you can actually have too large of an enclosure for many snakes. The reason for this, is that snakes are very prone to stress, and being in an excessively large enclosure can scare them. Imagine in the wild they are constantly hiding from predators, then, when they feel it's safe in the dark of night, they will venture out to hunt for food. Once they find their food, they will return to the safety of their secure hiding place until the next time around. Many species will not even hunt for food; rather, they will sit and wait for their prey to come along. They may also leave their den for sloughing their skin or finding a mate at certain times of the year. Many individual snakes feel very comfortable in captivity, although this generally comes with age and lots of handling. Snakes like these will often thrive in a larger than usual enclosure.
Snake enclosures can be made from a number of materials. Most commonly used is a melamine coated wood which covers all sides except the front, which has glass sliding doors. Aquariums can also be used, although a specialist lid should be bought or made rather than the original aquarium lid. It is essential when thinking about what type of enclosure you use, you think about these 6 'SSSHHH' factors:
1) Safety – Can the snake or owner injure itself from the enclosure or any appliances held within?
2) Secure – Can the snake escape through any small hole or cavity?
3) Size – Will the enclosure be appropriately sized?
4) Heating – Is the enclosure able to regulate the temperature properly?
5) Humidity – Will the enclosure last well in humid conditions? Is there enough ventilation for the moisture to escape?
6) Hygienic – Will the enclosure build up a lot of bacteria in small cavities? Is it easy to clean?
By following the steps above, you can have a suitable enclosure made from a variety of materials.
Décor
Décor in your tank serves two purposes. First being extra cover for your snake and second, allowing for a more natural and pleasing appearance. When choosing décor, think about the safety of the snake. Make sure that whatever you decide to use, it is securely fixed and that no rocks, wood or anything heavy can fall and possibly injure, or even kill the snake. You must also make sure that everything used is parasite free. If anything has been picked up from outside, or has originally come from outside, such as cork bark, you should either boil it, or place the item in the oven at 200 degrees Fahrenheit for approximately 30 minutes. Freezing works for some parasites, however others have been known to survive months in freezing conditions. Some parasites found in English conditions last winters in minus temperatures, so it is not entirely effective.
Once all your décor is parasite free, it is then safe to place inside your enclosure. As a general rule, if you can put pressure on an item to knock it down, an adult king snake is also capable of doing this. When positioning rocks or heavy objects, make sure they are completely secure. If it is still uneasy, screw them or use superglue to fix them securely. If it is not possible, the rule is simple: Do not place the item in the vivarium!
If you decide to go for a large enclosure, you must provide plenty of cover and hiding areas. A hiding place can be anything from an ice cream tub with a hole cut out to a naturalistic piece of cork bark. There are many brands of fake plants and décor you can use which is both safe for the animal and pleasing to the eye. Cork bark is available from almost any reptile pet shop in the UK, and can be ordered in if they do not have it in stock. This is excellent cover for any reptile and is 100% natural. One thing you must consider when thinking about the size of the vivarium, is the bigger you go, the more hiding areas you must provide. I recommend at least one hiding place per foot in length of the enclosure.
NOTE: Never use sticky tape in an enclosure; this is an accident waiting to happen. Believe me; removing sticky tape from any snake is no easy task!
Heating
Kingsnakes require a thermal gradient, meaning they must be allowed to move around the enclosure to find their required temperature. The hot end of the enclosure should be 86-90ºF while the cool end should be approximately 78-80ºF. During the night, the temperature should drop to a more constant overall temperature of 74-78º
In my opinion, the ideal way of heating a kingsnake enclosure is to use a power plate. This is a small thin square plate, about 25mm thick which is screwed into the top of the vivarium. It does not need to be protected, as there is no way a snake can grip onto it. It is almost invisible to the eye as it simply sits on the ceiling of the vivarium. The only brand available in the UK is HabiStat Reptile Radiator; it is 75 Watts and is sufficient for any vivarium up to 4ft long and possibly larger. It produces no light and therefore in a vivarium you will need a form of lighting as well. A power plate should be used in conjunction with a HabiStat Pulse Proportional Thermostat, which will stop the power reaching the power plate as soon as the temperature goes above the setting, and turn back on as soon as it is too cool. This is one of the most accurate thermostats on the market today.
Ceramic heaters, spot bulbs and heat mats are also ways of heating a vivarium. These all have their advantages and disadvantages, but in my opinion, none quite weigh out to be as good as a power plate.
Lighting
Kingsnakes are primarily nocturnal, meaning they venture out in the dark of night. This is when their main predators are sleeping, and their prey is awake. This is not to say though, that they never see the sun, or any form of lighting for that matter. They will often bask in the sun during the day in the wild, so lighting should be offered.
Having artificial light in a vivarium is aesthetically pleasing to the owner, and is a good addition to a snake's enclosure. They will use this as a photo-period, and their regular time clock will generally adjust to the settings on which you have your light set to.
They do not require any form of special lighting, such as a D3 Ultra-Violet light commonly used for diurnal species. An Arcadia Natural Sunlight Fluorescent Lamp is a good form of lighting. This comes in lengths of 12" up to 48" and I suggest you use the largest size able to fit inside your vivarium.
Humidity
Californian Kingsnakes are generally not exposed to a high humidity range in the wild, and in captivity you should not worry about controlling this. A fairly dry environment should be provided, although raising the humidity when the snake is coming up to a slough may aid in shedding it's skin properly.
Feeding
Hatchlings should be offered pinky mice, and as they grow the mice should become larger. An adult kingsnake should be fed on large size mice or small weaner rats. Hatchlings should be fed on a regular basis, every 4-5 days is ideal. Their metabolic rate is very high and as they are growing, they need a lot more food to keep them going. Adult kingsnakes need feeding once every 2 weeks on 2 large mice. The only exception when they should be fed more is bringing them out of hibernation, getting them into condition for breeding and then, fattening up females for egg production. An egg-laying female should be fed more often than normal, once a week on 2 large mice.
