Does she eat at all? I have and eppie that lays about 4 eggs a month. Other than being fat, she acts normal. Some sharks, like the short tail nurse shark will stop eating for several days and rest before depositing eggs. There is no such thing as a banded cat shark so my guess is that you have a brown banded carpet shark. I would not expect a dramatic change in behavior before dropping an egg, though I have never witnessed one lay an egg.

Bacterial infections, intentional blockages, over eating and malignancy can cause the symptoms you describe. Feel her belly. Is should be soft and uniform. If she feels bloated, full of air or tense, I would treat with antibiotics. If she is infected, the gill movements will be rapid and she will likely appear weak, not just tired.

As for eggs, a shark can lay infertile eggs like a chicken. They are fertilized before, in vivo, not after releasing them. The females can store sperm for possibly years.

Hope this helps and good luck.
