Using your history - whenever I have an owner present to me with a case similar to what you write:
- Middle aged to older cat
- Chronic vomiting
- Weight loss
I discuss that there are a certain group of disease processes which tend to be more likely.
Possibilities include, but are not limited to:- Hyperthyroid (overactive thyroid)- Diabetes- Kidney Disease- etc.With this information - the first step to evaluate underlying causes would be basic bloodwork checking the sugar level, thyroid level, and organ values.
If those tests are non diagnostic - meaning they do not show an answer as to what is going on - the next test would then be an abdominal ultrasound. With that said - what would I be looking into with the ultrasound? Why do I recommend this? Of course it would be part of a thorough evaluation when there is chronic vomting and weight loss - but notably I would be looking to see if there was evidence of intestinal thickening due to either cancer such as Lymphoma or Inflammatory Bowel DIsease.
