Okay, we have some stuff to cover then.
1. figure out which type of snake you would like ie boa, python, rat snake, kingsnake, garter, etc. And then from the group you like the best, pick something out that doesn't grow more than 5 ft and is gentle and hardy. Off the top of my head, a cornsnake or a California king are among the best for novices. Avoid burmese and reticulated pythons like the plague! They aren't bad snakes, but they grow huge and need an experienced keeper with a big budget.
2. random snake facts and trivia for you. Cared for properly, snakes can live anywhere from 15 years to the record of 47 years. It's an extraordinarily rare snake that shows affection. Usually they just tolerate us (and occasionally they'll grudgingly enjoy our company)
. Generally snakes need to be fed every one to two weeks. They need water at all times. Keeping a log for records is recommended. They need a place to hide, and in their hide, it's best if they can have contact with it on all sides to feel secure.
3. price... this is the tricky one. A nice well-started baby snake that eats frozen/thawed mice and is a good beginners species can usually be bought for between 20 to 100 dollars. There are many more expensive nice snakes too, but there are many wonderful critters in that low range. Then of course, there's the food, heat source (no hot rocks!) terrarium with secure sliding top, rheostat or thermostat, thermometer and humidity gauge, electricity costs, etc. The supplies and maintenance are where the real costs lie.
4. Research. There's a good site called www.anapsid.org just surf around there and you'll get a lot of facts. The Barrons series of books have good information, as do some others. And of course you can ask here. Good luck!
