BALL PYTHONS + RODENT FEEDING
Ball pythons, especially babies, are notoriously difficult to get feeding.
You should really only buy a Python regius if it was guaranteed to be feeding already on defrosted rodents...ideally, see it feeding yourself.
I would not recommend that you ever use live rodents, they can do a lot of damage to a snake in a confined space.
Place the defrosted or fresh-killed food on newspaper or a plastic tray so as not to pick up any substrate. If the snake will just go to the rodent and start to eat it - FINE !
If it shows little or no interest in feeding use defrosted rodents held by the base of the tail with proper "feeding tongs" - move the mouse around the head of the snake and try and provoke it into striking at the mouse. It may take 30 minutes or more to get a new snake to strike.
WHAT SIZE RODENT TO FEED?
For snakes under 4 feet - measure the widest part of the head of the snake - - - the rodent should be twice as fat as that measurement.
For larger boas and pythons the rodent should be no fatter than widest part of the body of the snake.
You should ideally only feed ONE rodent every 7 days to a snake this size.
A "normal" meal for a snake should take about 10 minutes to ingest and swallow.
If the snake eats quicker than this then the rodent is too small.
If it takes longer than 30 minutes, or is obviously struggling with the size of food or regurgitates it within 48 hours in ingestion – then the rodent is too large.
Next feed offer the next size up or down as appropriate.

I suggest you offer a defrosted rodent, warmed naturally to room temperature.
Providing you supply the correct temperature gradient a snake will digest a meal in 5 days and then poop; you then let the gut rest for 48 hours and then offer the next meal.
Apart from replacing the snake in the vivarium, avoid handling for 48 hours after feeding or it may regurgitate a semi-digested rodent [not at all a pleasant experience to have for you - or the snake].
