one rat not enough?

So after feeding my 3 foot female ball python a medium rat 4 hours ago, she is very active again, doing what she usually does when she's hungry. I have never seen her do this before, does she need more?

A medium rat is enough for her. What is her weight?

That's a good question, I should go grab a scale from Wal-Mart tonight =/.

Weigh the rats too if you can. I see "sizes" tossed around a lot. A medium rat is an adult rat.

Regards,
