i think some corns just have sensitive tummys too, one of my lil uns will sometimes try an regurge after meal when touched, even if its been a couple of days.

she prefers to digest slowly and stays on the cool side or in the middle, only ventureing to the warm hid occasionally, whereas my other 2 corns use the warm hides to digest in, recently she has discovered the joy of the gecko's red bulb and as the vivs are next to each other and are glass she curls up on her lil log which is quite big and is almost touching the glass right by the bulb, safe cos the bulb is in the next viv but nice an toasty lol, cute to look at too.
