hungry

I fed my bp on saturday on and she has been so atcive
What is going on

anybody

Its possible that you didnt feed the bp an adequate sized mouse/rat
or
The ball is stressed. Being overly active is a sign that a ball python is stressed out. I would check the husbandry and make sure everything's up to par. Also consider how much you handle the ball and what not. Most likely something is off in the husbandry to make a ball antsy. Most times after feeding balls prefer to escape to their hides and let the heat help them digest their food.

As mentioned check temperatures to make sure your not too hot.
Might still be hungry, might just be you notice the activity level more right now.
Some snakes don't follow the rule book and get active after eating, not sure why, but I see it in some of mine after eating.
It's much more common for them to go straight to their hot spot to soak up some heat and start the digestive process.
Does your set up have belly heat?
What size is your snake and what size is the prey item?

She is a 21 inche 110 to112 gram 10
