You are correct, No one can tell you what you spend, BUT...
How are newspapers free? They cost me $1.00 each.
A bag of pine is about $7, a 25lb bag if Mazuri is about $25.
I bet the electricity that an oil filled heater uses yearly is $15 per snake.
I don't want to argue about this, if you only spend $15 per year per snake then![]()
