I have a dsh neutered male cat (11 mos old) (lost litter mate at 4wks old)has ongoing upper respiratory conditions,lethargy, loss of appetite, no vomit or diarhea, been on and off antibiotics for the last 10 months, been tested twice for feline leukemia and aids, both times negative. He is currently being treated for suspected hemobartonella, blood test 2 weeks ago showed low red cell and white cell counts but the last blood test one week ago showed a slight improvement in red cell count but decrease in white cell count. What else should we be looking for? Thanks, Pam email:XXXXX@XXXXXX.XXX
