Watery stool

[crs]

I noticed today that my leos stool was large and watery, but it did eat 20 mealies the day before and this is the first day that it has had watery stool. Should I take it to the vet imediately or should I wait and do (try and do) a fecal myself?

And I forgot to mention that she is on the warm side of the cage most of the time.
