There could be several causes of vomiting in your cat - gastritis (inflammation of the stomach wall), pancreatitis, inflammatory bowel disease, intestinal parasites. The vomitus is yellow because it is mostly stomach acid and bile. This is not unusual if the stomach is empty of food when the cat vomits. I would recommend withholding food for 12-24 hours (small amounts of water is ok) and see if the vomiting resolves. If Toffee continues vomiting then I would recommend you take her in to the vet to be checked out.

    Stomach bile is yellow in color - so yellow fluid is what you will normally see if your pet is vomiting with no food in her stomach. So the yellow color itself is not cause for concern :) Without more information, it's hard to say what might be causing Misty to vomit - this can be due to anything from a minor upset stomach, to a more serious problem such as an intestinal obstruction or pancreatitis. If Misty has been vomiting for less than 24 hours and is acting normal otherwise, you can try withholding food for the next 12 hours to give her stomach a chance to settle - then feed a bland diet of plain boiled chicken or chicken-flavored baby food for the next day or two. If this doesn't help, or if she has been vomiting for several days already or is having any other symptoms such as acting lethargic or not wanting to eat, she needs to be seen by a vet since these can be signs of a more serious problem.
