Won't tell how much I have spent so far because the number are high for most average keeper, now what you need to tell yourself is that if you have one snale and spend $200 on caging and $100 on a reliable thermostat you are looking at a very cheap investment considering your pet will live 30 years or more that's only $10 a year.
And feeding is not gonna cost you all that much compare to any other pet you could have, same with vet care, if I compare a snake cost versus one of my dog cost it's nothing.
