1st rule of snake keeping: Don't tell anyone about snake keeping.

j/k
The real 1st rule about snake keeping: Find the snake you want/are capable of keeping and cater to the <b><u>SNAKE'S</u></b> needs. Don't make it cater to <b>YOUR</b> needs. It's needs are life and death, yours are saving $50.
Pick the milk you most like, get the enclosure all set up according to the snake's needs and then get the snake. Everyone wins!
