There is one species of wild cat on Trinidad and Tobago and that species is the ocelot. This is confirmed by the geographic range of this well-known wild cat species as presented by the IUCN Red List. The people who run the Red List are the people who should know best as to whether an animal exists or no longer exists in a particular area. As at May 2014 the ocelot was resident i.e. it existed, in the following countries: Argentina, Belize, Bolivia, Brazil, Colombia, Costa Rica, Ecuador, El Salvador, French Guiana, Guatemala, Guyana, Honduras, Mexico, Nicaragua, Panama, Paraguay, Peru, Suriname, Trinidad and Tobago, United States (Texas, Arizona), Uruguay, Venezuela. As you can see Trinidad and Tobago is in that list. That is the latest data. Not great but the best we have.
A Facebook posting by the Emperor Valley Zoo tells me that in Trinidad the ocelot is protected under the Conservation of Wildlife Act. Despite being described as an environmentally sensitive species they are sometimes illegally hunted on the islands of Trinidad and Tobago. Trinidad is the larger and more populous of the two major islands of Trinidad and Tobago.
