When preparing a pre-killed animal for your pet, thaw it by running it under warm water or setting it in the sun. Take care not to let a pre-killed meal sit for too long, though, as harmful bacteria can start to form on it. Baby California Kingsnakes do well eating one pinky (hairless newborn) mouse once every week or so.
A Hillbilly Guide: The Speckled Kingsnake | PetHelpful
Kingsnakes and milksnakes come in a variety of sizes, so a cage can be chosenaccording to the adult size of the snake, although smaller cages can obviously be usedwhen the animal is growing, in fact, smaller cages for young snakes can be better in someinstances because it is easier for the snake to find the food. All baby kingsnakes andmilksnakes can be housed in an enclosure the size of a standard ten gallon aquarium, oreven the size of a five gallon aquarium, depending on how often one wishes to purchase alarger enclosure as the animal grows. Most adult kingsnakes can be housed in a standardtwenty-gallon long or thirty-gallon breeder aquarium. The idea is to have an enclosurelarge enough to provide a thermal gradient. Many hobbyist and professional breeders do notutilize glass aquariums because of their bulk and weight. If you are planning on owningmore than ten or so snakes, it may be advisable to purchase a rack system or stackablereptile enclosures. A rack system looks similar to a chest of drawers, there are severalrows of cages, one on top of the other, all encased in one larger cabinet-like piece. Ineach row there are either one, or several (depending on the size of the individual cages)plastic cages. These cages pull out from the cabinet like a drawer does from a chest. Manyrack systems are "lidless"; they are built so that the cages slide back in flushwith the bottom of the next row, which acts like a lid. Running along the back of the racksystem is a line of heat tape which heats one end of the enclosure, providing a thermalgradient. Heat tape must be controlled by a thermostat in order to provide the ideal"hot spot" temperature and to avoid a fire hazard. Rack systems allowherpetoculturists to keep snakes more efficiently and to provide the correct thermalgradient. Other options for reptile housing include manufactured cages, there are manycompanies specializing in custom reptile enclosures, if you are interested in these, askus for a reference.
