If you’re fortunate enough to catch a glimpse of a margay, you might think you’re looking at an ocelot cub.

The two species look remarkably similar, sharing beautiful rosette patterns in their fur, intense eyes and prominent facial stripes.

But ocelots are medium-size cats that can top out at 35 or 40 pounds, while margays are even smaller than domestic felines, weighing between five to nine pounds.

Living in jungles teeming with life, margays have a distinct advantage that allows them to escape land-based predators while making them a threat to monkeys and other critters living in the branches — they are outstanding climbers with unique biological adaptations that allow them to do things other cats cannot.

The most dramatic example is their ankle joints, which allow them to rotate 180 degrees as the little spotted cats anchor themselves to trunks and branches. As a result, margays don’t just climb with speed and ease, they are capable of swiftly evacuating trees by climbing down head-first like squirrels.

Other cat species lack that adaptation, which is one reason why we often hear about domestic cats who find themselves uncomfortably high up in trees or on utility poles, refusing to come down for days despite hunger and coaxing by humans trying to help.

Margays are outstanding jumpers in addition to their unrivaled climbing ability, able to leap six to eight times their own height. It’s easy to see how these diminutive cats can intercept birds and monkeys far above the jungle floor in addition to hunting terrestrial mammals.

Indeed, using their large tails as a counterbalance, margays traverse branches with a swiftness and sure-footedness that rivals the gibbon.

The jungle’s tricksters

They’re also remarkably clever. Scientists have documented margays mimicking the vocalizations of monkeys, their favorite prey. In one documented example, a margay imitated the call of a baby tamarin, then ambushed the adult tamarins who approached to investigate the sound.

That’s a surprising adaptation for a cat species, and we should be thankful they’re tiny. The thought of tigers or leopards with that ability is terrifying.

Margays are solitary and due to their size, they’re both predator and prey. Because of that, these tiny cats spend the majority of their time well above ground level and are usually found deep in old growth jungles where they can blend into dense vegetation, hiding among leaves and branches, where their coat patterns help them blend in.

Like all wildcats, margays face increasing pressure from habitat loss, poaching and other threats, and they’re classified as near-threatened on the IUCN Red List.
