Cellar Spider Body Size

[Suz871]

My cellar spider has changed its shape and color, in the past 11 days. I am new to the world of arachnids so maybe this is a normal occurrence for the body shape and size to change. I am just hoping there is nothing wrong. So far, he or she has had a diet consisting of a small beetle type of bug on the 12th. Since then, I have observed black ants, as to what was on the menu. The most recent meal consumed was on the 18th. The first photo was taken on the 10th of this month and the second photo I just took this morning.

I moved one into my bathroom for mosquito control. Fed it a few times to make sure it could set up shop and boom, egg sac

Has it molted since you've observed it?

Not that I have noticed. I was wondering if that’s what it could be.

It's either that, just well fed, or gravid

It just looks like she ate a big Meal.
