If the meal was too big:
Well don't handle her & keep your fingers crossed, they generally digest it but may be bloated for a couple days. What actually happens (when & IF it's bigger
than they can handle well) is that some spoilage occurs & some gas can build up, but usually they'll get it down...though they may regurgitate instead, which is
bad for them & really bad for your air quality . By the way, your hot side is also too cool, so that's not helping either. She needs heat to digest.

But, you say she is bigger towards the tail end? That suggests she may be constipated, but nothing you can do right after feeding her anyway. My biggest
concern was whether or not she is able to digest what you just fed her.
