Pet's info: Cat | Mixed Breed | Male | neutered | 1 year and 7 months old
My cat was diagnosed with Brugia spp. Infection and the doctor started the treatment with Doxycycline dose 10mg/kg (vibravet) twice a day. He told me that my cat is infected with heartworm as the microfilariae of brugia is found in blood test (we did the heartworm ag, it was negative). But I am confused as I did some research and found that the heartworm is Dirofilaria immitis not brugia, are they the same thing? How would you treat a cat with this infection?
