My First Snake, My Ball Python!

[NicoleElaine]

So My Best Friend And Me Went Two Days Ago To Pick Up A Snake She Had Found On Craigslist, We Get There And The Guy Has Two And Is Just Selling The One To My Friend We Ask About The Other And He Says He Is A Very Aggressive Snake He's Missing An Eye I'm Just Gonna Kill Him No One Want's Him, Me Being The Animal Lover I Am Decides To Tell Him I'll Take Him So He Won't Kill Him. I Now Have A 3 to 3 1/2 Foot Long Ball Python And No Idea How To Take Care Of Him. I Do Have Him In A Tank With A Locking Lid And It's Got Water And Some Broken Branches And A Rock So He's Not The Only Thing In The Tank And I Fed Him A Live Medium Sized Rat The Same Day I Got Him He Had It Eaten In A Matter Of Five Minutes. Any Thing I Should Do Or Know To Make Him Happier?
