Cat!
Over at Discover Wildlife, Catherine Smalley has the answer:
The jaguarundi is one of the strangest-looking cats in the Americas. Long-bodied, short-legged and sleek, it has more than a hint of otter or weasel about it, which explains why it is sometimes called the otter cat.
Yet this elusive hunter is very much a felid, and a close relative of the puma. Found from northern Mexico right into South America, the jaguarundi is unusual not only for its shape but also for its habits, being more active by day than many of its feline neighbours.
The jaguarundi ranges from northern Mexico through Central America and across much of South America east of the Andes, reaching as far south as central Argentina. Historically, it also occurred in southern Texas, though it is now thought to have disappeared from the USA.
