Excessive vomiting in older cat
I have an approx. 7-year-old long hair cat who has always been very underweight. I have had her for 4 years (took her in as a stray) and she has always had a vomiting problem. I was concerned at first, but my vet at the time said "oh, she's just a skinny kitty." So I didn't worry about it. I've since moved and changed vets. My new vet was almost over-the-top in her concern for my cat. We've since been through a series of tests, without a real diagnosis.
Symptoms (keeping in mind she's been this way for 4+ years):
- Meager appetite
- Very thin, about
- Vomits near daily, at times whole food, others just liquid (bile?)
- If I feed her higher fat food (canned, tuna) she will eat it eagerly, then turn around and vomit it all.
We started with a trial run with an allergen-free cat food (Science Diet), but there was no reduction in vomiting.
The vet ran a CBC w/ dif which returned with elevated white blood count. She was subsequently de-wormed; a repeat CBC showed no change in white blood count (still elevated).
I was told she either had an intestinal disorder that was causing her GI to inflame and reducing her nutrient intake, OR Feline Leukemia. To be sure, they would need to do a exploratory surgery (2K). The alternative was a trial run of steroids (Prednisone), based on the assumption that it was not Feline Leukemia. She has been on this for about 5 months and I'm not seeing any noticeable improvements. I don't know why they didn't run the blood test? I assume that if she had Leukemia she would have already died? Either way, the impression I got was that the trial run of steroids was my vet's last idea before surgery.
My question is, what do I do next? Is she really "just a skinny kitty?" I feel a little mistrustful of my vets, former and present, at this point. Any suggestions would be appreciated.
