I need help setting up an habitat for my snake.

I'll be getting a Corn snake in a few days to a week (hopefully), and I've looked up information on the internet of what would be included in a tank, however, could somebody please maybe show me how they set theirs up, or give me some advice, anything would be appreciated. Especially since the snake will be a baby, I'm pretty sure I have to buy it from a pet store, not my first choice to, but it's my only option, because it's too exspensive to buy from a breeder on the internet and everything. I'd like to know what size tank and everything would be a good choice to get since it will be rather small, any help would be appreciated, thanks!

Hi There!
It's great you want to get a snake! and are setting up the cage before you bring your new baby home!
My basic set up is (the cage), a heating mat (on the outside bottom) that covers about 1/3 the bottom, 2 hides (one over the heat mat, one on the cool side), water bowl- on the cool side, I use paper towels as substrate for all my new snakes- to make sure there are no health problems. I switch some of the snakes to aspen after the first or second shed. addtitonal items would be a temp gun, digital thermometer (you need to make sure you have the correct temps). I have all my cages in rooms that have ambient sun light so I am not required to use light fixtures. If you don't have windows you might want a light fixture to simulate light & dark.
You can put branches and other "furniture" in the cage- I also use a thermostat to help control the temperatures better but for one snake you could opt for a rheostat (you just have to adjust the settings before you put the snake in the cage) rheostats are usually a lot less expensive!
Just make sure the environment you create is stable before you put your new baby in it's new house! I hope this is helpful! and good luck!
I'm sure you will get some other suggestions from the forum soon!
