Nini 's blood work showed a very low red blood cell count, which means he is anemic. There can be many causes for anemia but in such a young cat, the most likely causes are infectious. The two most likely diseases would be either a viral infection (FeLV or FIV) or a red blood cell parasite called Hemobartonella.We should run several tests in addition to what we already ran to try and figure out the cause of his anemia. We also should run a test that looks at how well his bone marrow (where red blood cells are made) is working. Here are the tests I am recommending as well as their cost. 1) Reticulocyte test $592) FeLV/FIV test $923) Hemobartonella test $133 nini did all these test on August 10 and all the tests results showed he is fine.
