Oh this poor kitty!!
May God bless you for helping her!!
A bloated belly can be a sign pf pregnancy, worms, infection, starvation or a disease called FIP (God forbid).
As long as she is eating she is not feeling too bad as sick cats wont eat.
I would have her seen by a vet and have it documented that YOU provided medical care for her.Anyone who would abandon a cat with no food or shelter does not deserve to get her back nor would their request stand up in any court.
Please let me know how she is. I will always be here for both of you.
Warmest best wishes,
