Also keep in mind that a large savanna can take off your finger if you are not familiar with reptile handling. My girl frankly DOES NOT bite, but absolutely CAN.
I got grazed with a tooth ONCE while feeding cockroaches to her by hand, and that was bad enough. A guy at a pet store near by, worked there in the reptile section forever, and had a nasty savanna come in and nearly lost his thumb. The animal was only a foot long, and the guy's thumb was broken, and needed stitches.
I would not suggest a savanna as a first reptile, frankly.
