A twelve-year-old, spayed female Siamese cat was presented for health screening. Abdominal radiography revealed a large amount of mineral opacity substances of various sizes and shapes, along with mild gaseous dilation proximal to the lesion. Ultrasonography showed hyperechoic surface with acoustic shadowing at the ileum and wall thickening of the ileum. Enterotomy was performed to remove the foreign bodies, which were numerous hairball- and stone-like objects. Analysis of the enteroliths revealed a composition of calcium phosphate. Although enterolithiasis is considered rare in cats, it should be included in the differential diagnosis when numerous pebble-like mineral opacity lesions are observed.
