He did state that the dragon was in a different place each time he entered the room. Some females dont dig, but rather pace. I have one who paces only. Also he stated he felt bumps, which sound like a sign of eggs. But also could be impaction. I just would have thought that a impaction would be felt as maybe one hard lump, not several.
A few days to a week before laying a female may stop eating. If she doesnt have a suitable laying spot she may strain, push alot and poo alot. After awhile she will only pass urates as there is no food to be digested and freshly pooed. Eventually she will not push anything out!
I am not saying it isnt impaction. I am just saying it could also be eggs. It cant hurt to try a laying site. As long as there is no prolapse.
I would have suggested mineral oil, but if it is eggs, it may cause her to have ntestinal upset as there probably isnt any fecal matter left in her digestive tract. Also if it is a fake plant stuck in there, giving mineral oil may lodge it in more and may even cause a tear in the intestinal tract. I know with humans it is not a good idea to give a laxative for children who have swallowed a large object (especially one with sharp edges).
I highly recommend a vet trip. But if he has to wait a day or two, if I were him I would try a laying site, liquids and a new substrate.
Only a vet can rule out or diagnose a problem. All we can do is offer suggestions. Lindsay
