Conus catus, common name the cat cone, is a species of sea snail, a marine gastropod mollusk in the family Conidae, the cone snails and their allies.

[2] Like all species within the genus Conus, these snails are predatory and venomous.

The body whorl is striate, the striae rounded, usually obsolete above, granular below, olive, chestnut-, chocolate- or pink-brown, variously marbled and flecked with white, often faintly white-banded below the middle.

In the variety nigropunctatus, the shell is colored as above and encircled by series of chocolate-colored dots.

[3] This species occurs in the Red Sea, the Indian Ocean off the Aldabra Atoll, Chagos, Madagascar, Mauritius, Tanzania and KwaZuluNatal; in the tropical Indo-West Pacific Region (Papua New Guinea, Marquesas, New Caledonia); off Australia (New South Wales, the Northern Territory, Queensland and Western Australia).
