I'm afraid she didn't make it.
Last night she was struggling to pass urates, so I held her in a shallow bath of warm water, which did seem to help. She passed some VERY solid looking urates and we noticed what looked a lot like worm or worm segments (VERY tiny), not moving so I presume the worming medication worked and maybe the ReptaAid got her system moving again.
However, she continued to struggle and something that looked like pale flesh started to project from her vent, I was afraid she was prolapsing with the effort. The bulge was not diminishing.
She kept struggling to pass something, but eventually it was too much and she died in my hands.
I did an autopsy, half expecting to find a mass of worms in the bulge, but it was a large amount of soft faecal matter. Her intestine was very enlarged behind it and totally empty beyond it, but I could not see what had been causing the blockage.
There were no obvious worms in her intestine (at least that I could see, you have to remember how tiny she was).
However, what I had thought was a prolapse came away freely when I cut her vent, it just looked like a pale blob of muscle tissue. Maybe a worm head (if so quite large and featureless) or maybe a piece of undigested gecko tail (if so it looked totally undigested or decayed, and her last meal was a month ago)?
I don't know. I'll post the pics when I get time to download them.
At the moment I think it may have been as follows:
I gave her a live gecko (instead of the normal F/t) 3 weeks before this started, as she had not been feeding well - possibly it had intestinal parasites.
If so, the worms (or something else) caused a blockage in her intestine, and faeces started to build up behind this, but she could pass urates. Sensibly (I know I anthropomorphose) she refused more food.
The wormer medication worked, and possibly the ReptaAid got her digestive system going, and MAYBE if I had had the courage to pull what I thought was a prolapse out, she may have been able to pass the faeces, but there was no sign these were moving when I did the autopsy.
My consolation is that this could have happened if she had been in the wild, and that her chances as the runt were reduced anyway. I'm sorry to lose her though, she was a sweetheart.
