Why is my cat no longer eating and always vomiting?

Original Question: My 2 ½ year old spayed, semi feral cat can be petted but not picked up. Lucy has lived in my guest room since July and she has quit eating/started puking in early December. The vet did a urine and blood test no December 7 and nothing was wrong, no temperature and on December 12 the vet gave fluids under her skin and gave her a shot of Cerenia. The shot stopped the puking and Lucy resumed eating but late last week she stopped eating and started puking again. Do you have any suggestions that I can offer to the vet when I return? - Leona

Hi Leona,

Thanks for your question.

There is very little detail in your question which makes it difficult to give you a specific answer.

Vomiting in cats can be caused by so many reasons. It could be ingestion of foreign material, toxin ingestion, helicobacter infection, bacterial infection, viral infection, parasitic infection, anxiety, thyroid disease, kidney disease, diabetes, inflammatory bowel disease, and cancer to name a few. It will likely take more diagnostics to determine the cause. So far you have simply used an anti-nausea medication, antacid and appetite stimulant. These are basically treatments for the symptoms, not an actual disease process because the cause is unknown at this time.

The next steps I would do is to perform radiographs, a fecal test, fecal culture and speak to your veterinarian about a more specific treatment trial or longer course of supportive medication. If you still do not see improvement, the next test I would recommend is an abdominal ultrasound. I think this will likely find the cause of the vomiting and inappetence.

I hope this helps. Good luck.
