Some updates about this situation. First off, I immediately made a vet appointment and got in early morning on July 2. The vet said they didn’t feel anything that seemed like eggs and that there didn’t seem to be an issue and to monitor her.
On the morning of July 4th, she passed these things shown below, which were similar to the egg looking things from before, plus some chained structures I hadn’t seen before. Also seemed to be a lot of liquid like egg goop.
After this, she stopped laying inverted, stopped twisting, and generally stopped acting visibly uncomfortable as she had been before. I assumed she must have passed everything and should start eating again soon. I updated the vet and continued to take their advice of closely monitoring her.
After 2 weeks of not eating, I pressed the vet for more we can do to rule out something still going wrong. They referred me to another place to have ultrasound done, and I had to wait another 2 weeks to get an appointment for that. During the wait she still hasn’t eaten, but still never looked uncomfortable again.
Had the ultrasound done in early August and everything came back normal. No blockages, no objects in the reproductive or digestive tracts, no abnormal organs. Which was a relief, but it doesn’t help fix that she has absolutely no interest in food.
Then I had a general blood panel done as well but now that didn’t come up with anything significant either.
I’m at least cautiously optimistic and continue to monitor her for any apparent decline; and she continues to seem ok except for her appetite, which used to be absolutely ravenous.
If anyone has any other suggestions, experiences, or advice that could help me it would be very much appreciated!
