It is an important factor if you do not want to have a huge aquarium in the living room. The temperature required for this species is between 75 and 85 degrees. Unlike some other types of snakes the milk snakes do not need a temperature drop at night so there is no risk you forget to turn down the heater for the night and as a result hurt the animal. The issue of feeding is not a problem. The ones living in the wild usually eat small rodents but also birds eggs reptiles amphibians and invertebrates. They also may eat other snakes like I mentioned before. In captivity the most common prey are mice. For young snakes - pinky ones for adults - adequate to their size once a week. Cue the common adage is your refrigerator running? only this time don t fall for the joke.

If you are interested in learning more about these bottles there are two books currently available that provide some excellent information about how they were made and used along with some basic pricing information. The book are titled "Udderly Beautiful" and "Udderly Splendid" by John Tutton. Both give some rarity and pricing information but because of the large number of bottles produced they don t cover even a small fraction of the bottles produced.

Other sources of information are The National Association Of Milk Bottle Collectors and the individual web sites many of their members maintain.
A full grown snake however should be provided a 60 gallon tank in which it can stretch and move about as king snakes and milk snakes tend to be quite active. When selecting a terrarium for a king snake or a milk snake it is also very important to select one that can be secured tightly. These snakes have a reputation for getting out of their cages and for squeezing through even the smallest places. So spend a little extra on a terrarium with a top that can be latched. Maintaining the proper temperature is also important when it comes to keeping your snake healthy. Milk snakes and king snakes generally like their cages to be around 76 to 86 degrees Fahrenheit during the day but the temperature should drop down to about 70 to 74 degrees Fahrenheit at night.
