Hi Adie Dee,
I'm sorry to hear about your cat. I suggest that she is seen by a vet right away for xrays of her abdomen and bloodwork (as well as a complete exam). At her age the most common causes of what you are describing are a foreign body obstruction in the gut, a toxin ingestion, or inflammation of the GI tract. The most important thing to rule out is an obstruction as this could be life threatening and would require (in most cases) surgery to remove the object(s).
For now I would pull up her water for 6-8 hours to keep her from having anything in her stomach to vomit up.
If you can reach an emergency vet tonight I strongly recommend you have her checked out especially since this has been going on for 4 days and by now I suspect she is probably clinically dehydrated.

I hope this helps. Please let me know if I can be of further assistance.

Best,
XX. XXXXXX
