Customer Question

Hi, my cat has a stress based illness. Every 4-5 months, he get sick and his blood percent gets too low. He stops eating and loose %20-30 of his body weight. Our wet tells us to give him Ronaxan, but he vomits after 10-15 minutes. It is a fight for us to give it to him. Is there an alterntive treatment, or something that won't make him vomit? I hope you can help us. Thanks a lot anyways. Brgds, Kaan

I'm sorry that your question wasn't answered in a timely manner. To be able to help you and Asian, I need to know what this "stress-based illness" is that doxycycline (Ronaxan) is supposed to address. Such a recrudescing (relapse without cure in between events) and profound loss of weight and anemia suggests the feline leukemia virus (FeLV), kitty AIDS virus (FIV), or perhaps the blood parasite Mycoplasma haemofelis. Please respond with additional information and further questions or concerns if you wish.

1) A coronavirus antibody titer of < 1:100 is not suggestive for an infection with coronavirus. Nevertheless the formation of antigen-antibody complexes can lead to a decreased coronavirus antibody titer. The following changed laboratory parameters may indicate FIP infection in conjunction with suggestive clinical signs: 1) Serum proteins: a) hyperproteinaemia b) hypoalbuminaemia c) hypergammaglobulinaemia -> reduced albumin-globulin ratio (< 0.6 is suspicious for FIP) 2) Blood count: a) hypo- or aregenerative anaemia b) neutrophilia with left shift c) lymphopenia 3) Liver: a) hyperbilirubinaemia b) raised ALT3) Presence of a few reactive lymphocytes5) Presently the cat is not viraemic. Please note: the test result can also be negative in the very early stage of infection or in latently infected animals.


2) The result has been double-checked. 4) Basophils up to 200/ul are considered normal in the literature. *** Final report *** validated by Dr. Haas(Tierarzt) our printed reports are valid without signature.

I hope you can help us.

Thank you. The most alarming finding is a profound nonregenerative anemia. Nonregenerative means that Aslan is unable to replace the red blood cells he lacks. His anemia is so severe that without a blood transfusion you're likely to lose him. There is no clear cause of such an anemia in his complete blood count. I don't see biochemical test results which might be helpful. The next step would be a bone marrow analysis but this can't be done safely unless he's transfused first. Presumptive therapy for an immune-mediated hemolytic anemia with the immune reaction occurring in the bone marrow - hence, a usual regenerative IMHA being non-regenerative - with a corticosteroid such as prednisolone should be discussed with Aslan's vet at this time. Please continue our conversation if you wish.
