To determine the M-mode echocardiography reference measurements for Brazilian random bred cats in Rio de Janeiro, Brazil, Cats presenting for routine care were examined by M-mode echocardiography. Animals with free wall values ​​of the left ventricle and/or interventricular septum above 5 mm were not included. A total of 125 cats were included in the study. The correlation of the body score condition (BSC) with the echocardiography measurements was positive for left ventricle wall in systole (LVWs)  and left ventricular wall in diastole (LVWd) . The LVWd values of BSCs 3 and 4 were different , and those of BSCs 3 and 5 were also different. The LVWs values of BSCs 3 and 5 were different . The correlated effect between BSC and the echocardiography measurements was true for the left atrium , left atrium/aorta ratio, ventricular septum in diastole, ventricular septum in systole, LVWs, LVWd, left ventricle in diastole, left ventricle in systole, ejection fraction and shortening fraction. The M-mode echocardiography evaluation of cats is impacted by the animal’s body mass; therefore, the BSC must be taken into consideration when interpreting echocardiography measurements.
