Name: Clouded leopards and marbled cats have very similar fur markings, but for some reason those are called “clouds” on the big cat and “marbles”
At a distance, this slim little spotted cat does look like a miniature leopard. Up close, though, you’ll see that: Its legs are proportionately longer
Name: There is a little uncertainty about where “ocelot” comes from. Aztecs had the word ocelotl, per Wikipedia, but they used it more for jaguars.
