Hello, thanks for your question today! I am Dr. Drew, and I am a licensed veterinarian. I'll be happy to help you in any way I can.
I'm sorry to hear about Kobe's illness.
Unfortunately, some types of cancers won't cause changes in the white blood cell count.
Carcinoma, and secondary carcinomatosis, is often one of those types that won't lead to elevations in the white blood cell count.
Also, cats are masters at hiding signs of illness, until it reaches a point where they are no longer able to cope.
That's why we often are dealing with a very ill cat, once signs of a problem actually appear.
Typically, with carcinomatosis, exploratory surgery should yield some solid information, as the abdominal organs typically appear quite abnormal with this condition.
Thank you. I guess I was just so surprised by the acute onset and frustrated that all this diagnostic testing was yielding no results or concrete answers. I'm hesitant to put him through exploratory surgery but the most important thing to me is his comfort and quality of life.
