Appearance of feces when using GGG slurry?

[rockyr]

I have a very thin leo that I have been feeding the GGG slurry. She has been on it for 3 days now, and before that was being hand-fed Hill's critical care (on advice of vet). She eats the slurry eagerly, but since I haven't seen her actually poop since she ate it, I'm not sure if what I see on the tank floor is poop or if she is regurgitating it (she had problems with regurgitation of normal food previously--part of how we got to where we are now). It looks like there are urates in the spots I'm seeing, but without watching her actually leave the specimen, I'm not sure. So what do slurry-fed poops usually look like?

I feed my chameleon hand fed food as well (carnivore care). I can probably tell you if it's poo or throw up if you post a pic
