Godzilla has a very good point !
Normally, a double meal such as that wouldn't faze a young Ball Python. They will just curl up no the heat and be lazy for a little longer.
While it shouldn't be done regularly, it shouldn't hurt this once.
BUT!!!! If you do not have the correct heat to help that snake out to digest this big meal properly and quickly enough, you can run into issues. You never want a meal to start rotting inside the belly, before it can be digested.
Is your heat the "ambient" (in the air) heat on the warm side ? Does he have an additional heat source under him, such as belly heat ?
If your temps are the ambient temps on the warm end, that wouldn't be so bad, but he really should have some belly heat around 90 Fahrenheit (32 degrees celsius) while digesting.
If your temps are the warmest (ambient and / or belly) that you have, you should bump them up a tad. Your snake is probably just fine. He is just FULL and doesn't feel much like moving. But to be on the safe side, get your heat up to where it should be![]()
