One of my first carpet pythons (a 2 yr old coastal female pickup from an expo) had terrible attitude, she hated everything and was constantly alert to anything that came within striking range. At first I wanted to get rid of her, but after a while I began to learn how to work with her and it became a lot of fun. You learn a lot about handling snakes when you have to work with one that isn't friendly.

They usually make pretty good breeders, too
