Alright. Not sure exactly what this is, but I found this sticking to a leaf in the cage. It has whole mealworms in it and so I think it's throw-up, but not too sure why she'd throw up.
Hard to tell from the picture being blurry. Not providing proper temps for digestion after a meal will cause partialy digested droppings looking like that...if indeed that is a dropping. I see mealworms in there aswell, they can be a bear to breakdown also.
I know when I fed her it was a busy day for her. I took her to a show and it was a decent trip, so maybe that's it. And yes, they're mealworms. She usually has no problem breaking them down. At least as far as I've seen.
