I am sorry to hear your baby is having trouble
Can you tell me how old your baby is
Male or female
spayed or neutered
Is your baby urinating and defecating normally
Has there been any changes to the diet?
I may have additional questions but this will get us started
12 YEARS ,FEMALE , NEUTERED , SHE'S SHARES WITH ONE MORE CAT,
NO ALWAYS ONE SMALL CAN OF FANCEY FEAST AND SOME DRY FOOD, SHARES WITH THE OTHER CAT, MY HUSBAND TAKES CARE OF THEIR LITTER BOX AND HE'S NOT HOME RIGHT NOW, SHE VOMITED YESTERDAY A LIGHT BROWN LIQUID, THIS MORNING UNTIL NOON SHE DID HAVE PLENTY OF WATER , NOW I DON'T SEE HER GOING TO THE WATER FOR SOME TIME NOW, I OPENED ONE CAN TUNA IN WATER AND SHE FINISHED THE WATER FROM THE TUNA.
ok, thank you for the information.
There are several things that can cause inappitence and vomiting in older cats.
Diabetes and kidney disease are among the most common.

The most important thing is to get her to eat. Cats that stop eating are at risk for a condition known as Hepatic Lipadosis. When they stop eating their body begins to break down fat for energy. The liver can not process this additional fat. This can result in liver failure.
You did great offering the tuna as cats are very attracted by smell so offer tuna, salmon, clam juice or baby food in chicken or turkey. The baby food can be thinned with water and feed with a syringe if force feeding becomes necessary.
At this point a trip to the vet is warranted. I would recommend a full senior exam including blood work which will allow your vet to check the blood glucose levels, thyroid level, as well as the kidney and liver function.
I hope this has been helpful, please reply back if you have additional questions or concerns.
