My 11 year old neutered domestic short hair is very ill. He's in the "kitty hospital" on IV antibiotics for a very highly elevated white cell count. In the past two days, doctors have drained over 2 liters of fluid from his abdomen! He's refusing food and is dehydrated, but other than the WBC, all the other values in his blood work are good. No FIP, feline leukemia or any other viruses...no fever and no masses or tumors can be seen on x-ray. All his organs appear intact and normal. My baby has stumped all 3 of his doctors! Does anyone have any similar experience with their cats or even any guesses as to what may be wrong?
