My ball python isn't eating.

Temps are all sufficient.

Sufficient? What are they?

I only put the mouse in there when I am able to spend time around the tank, because I don't want any biting to take place. (My friends unattended ball python got its EYES eaten out by a rat).

Wow, your friend left that rat in a LONG time for it to eat the eyes out of it's snake.

As for my snake, I handle her everyday, it's been about three/four days in attempting to get her to eat, the only thing that's changed is her environment. She's had to switch tanks twice.

Why have you had to change tanks twice? Did you allow her 7 days to acclimate after each change? Whenever any of mine go off feed - they don't get handled again until after they eat. Handling is for your pleasure, not the snakes. Try not handling her, let her settle in, and offer her a mouse again in a week.
