Tilcayo cat diet & behavior: the ghost of the cloud forest
Straight answer: almost nothing has been formally published about the tilcayo's behavior. The species was described from very few known individuals. But the first ecological breadcrumbs are in — and they sketch the portrait of a classic small Neotropical cat: a nocturnal rodent specialist of the forest floor.
Diet: small rodents, almost certainly — and maybe more
Analysis of scat samples has turned up remains of small rodents, indicating that small mammals are part of the tilcayo's diet. That fits the pattern of every other tiger cat: across South America, Leopardus tiger cats feed primarily on small rodents, with birds, lizards, insects and the occasional frog rounding out the menu.
At roughly 1.4 kg, the tilcayo is one of the smallest cats in the Americas — right in the sweet spot for hunting rodents and other small vertebrates in dense forest understory.
When does it hunt? The nocturnal hypothesis
Camera-trap data suggest the tilcayo is nocturnal, active mainly at night. This matches its relatives: tiger cats across South America are predominantly night hunters, using low light and dense cover to stalk small prey.
Arboreal or terrestrial?
Unknown — and genuinely interesting. Many small spotted cats in the Neotropics spend considerable time in trees (the margay is famously arboreal, even using its rotating ankles to descend head-first). Tiger cats lean more terrestrial, hunting on the forest floor. Which way the tilcayo leans is one of the first questions its trackers hope to answer with camera-trap data.
Reproduction, lifespan, social life: the blank page
Nothing is published on breeding season, litter size, den sites or lifespan for the tilcayo specifically. One clue comes from the sanctuary individual: a male who arrived around 2017 as a young animal and is now about ten years old — suggesting the species can live at least a decade in human care.
