I was thinking of getting a pet snake. What can you tell me about them?
They are elongated, legless, carnivorous reptiles. Actually growing up we had a albino burmese python. She was 22 feet when she died of old age. 
Wow that is awesome. What did you feed your 22 foot python?
Rabbits and Chickens or Louisiana swamp rats. Lots of species of snakes have skulls with several more joints than their lizard ancestors which allows them to eat such large things.
Now that is a meal. I wonder how one acquires Louisiana swamp rats. Maybe set up some traps?
we got them from breeders. Snakes are found on every continent except Antarctica,
Maybe one day there will be a arctic breed acclimated to the cold climate.
I'm sure in time nature will evolve a snake that can handle a long, cold winters and short, cool summers.
I think I will start small. Probably get a garter snake for a pet.
That's actually the state animal of Massachusetts.
