Cutaneous calcinosis of the paws in cats is a rare skin disorder. In this report, we summarize our experience of two feline cases affected with this disorder. Those cats showed nodular structures on both hindlimb of pads that formed ruptured abscesses, and both cats also had chronic renal failure. In case 1, we removed several stones (4~2 mm), from the ruptured abscess which were mainly composed of proteins and calcium phosphate. Histopathologically, case 1 was diagnosed as local calcinosis. In case 2, creamy and pasty exudate fluid was observed emanating the ruptured abscess. A smear of the exudate fluid showed a chalky-like appearance on a slide, which was histopathologically indicated to be local calcinosis.
