Hi Vicki
I agree with CML, your cat needs help now!! I am very worried about your kitty. Not eating for 2 days is dangerous for a cat! It can cause a condition called fatty liver disease(hepatic lipidosis) that is potentially life threatening.
Your cat needs additional testing-ultrasound, x-ray, and blood work. In my opinion, she's got something else going on here.
By the way, I'm not sure what you meant by throwing up a stone. Could you explain this, please?
Best wishes

Emergency vets are open find one and get her there NOW! This is an emergency, she cannot go without eating for 2 days--this is serious. Please take her now.
