Plain-English summary
Three adult Siamese cats were diagnosed with a serious infection caused by Mycobacterium avium complex, which led to symptoms like loss of appetite, weight loss, and extreme tiredness. During their vet visits, the cats showed signs of anemia, swollen lymph nodes, and fever. Despite receiving antibiotic treatment, their condition worsened, and sadly, they either died or were euthanized due to their deteriorating health. Post-mortem examinations revealed severe inflammation in multiple organs, confirming the presence of the infection.

Abstract
Disseminated infection with Mycobacterium avium complex is described in 3 adult Siamese cats. All cats were the result of father-daughter matings. Clinical signs included anorexia, weight loss, and lethargy. Physical examination revealed pale mucous membranes, lymphadenopathy, splenomegaly, and pyrexia. Nonregenerative anemia was detected in all 3 cats, and macrocytosis was observed in 2. An antemortem diagnosis of mycobacterial infection was made on the basis of identification of acid-fast bacilli in tissue aspirates. The cats died or were euthanatized owing to clinical deterioration, despite antibiotic treatment. Necropsy findings included granulomatous lymphadenitis, enterocolitis, pneumonia, cellulitis, myelitis, and hepatitis. Organisms from the Mycobacterium avium complex were identified in bacteriologic cultures of tissue samples.
