Bay Cat
The Bay Cat, also known as the Bornean Bay Cat, is one of the rarest and least understood wildcats in the world. Endemic to the dense tropical forests of Borneo, this elusive feline is a true enigma of the animal kingdom. With fewer than 2,500 mature individuals estimated to exist in the wild, the bay cat is currently classified as Endangered by the IUCN Red List. Despite its elusive nature, it is a vital part of Borneo’s forest ecosystem, and scientists continue to unravel its secrets through rare camera trap footage and conservation efforts.
Meet the Bay Cat
Classification
The bay cat is a small, slender wildcat that bears a striking resemblance to its close relative, the Asiatic golden cat (Catopuma temminckii), but with some key differences. It has a short, dense, reddish-brown coat, though some individuals have been observed with a grayish hue. Its long tapering tail, which accounts for nearly 70% of its body length, often ends in a black tip and helps with balance and maneuverability in the dense forest canopy.
Adult bay cats typically measure 49.5 to 67 cm (19.5 to 26.4 inches) in body length, with tails extending an additional 30 to 40 cm (12 to 16 inches). They weigh between 3 to 4 kg (6.6 to 8.8 pounds), making them similar in size to a large domestic cat. Their rounded head, short legs, and large, forward-facing eyes give them an intense and mysterious appearance, further adding to their enigmatic reputation.
Where Does the Bay Cat Live?
Biogeographic Realm: Indomalaya
Continents: Asia
Subcontinents: Southeast Asia
Countries: Indonesia, Malaysia, Brunei
Habitats (IUCN): Forest
The bay cat is exclusively found on Borneo, making it one of the few wildcats restricted to a single island. It primarily inhabits dense tropical forests, particularly lowland dipterocarp forests, swamp forests, and montane forests up to elevations of 500 meters (1,640 feet). The cat has also been recorded in rocky limestone outcrops, peat swamps, and riverine forests, suggesting some adaptability to different environments.
Despite its adaptability, the bay cat is highly sensitive to habitat disturbance and is rarely seen in secondary forests or plantations. It relies on thick vegetation for cover, making it especially vulnerable to deforestation and habitat fragmentation. The rapid conversion of Borneo’s forests into oil palm plantations and logging sites has significantly reduced its habitat, pushing it further into remote areas.

Due to its secretive nature, very little is known about the bay cat’s diet. However, like other small felines, it is presumed to be a carnivorous hunter. Observations suggest that its diet consists of:
- Small mammals – Likely preys on rodents, squirrels, and possibly small primates.
- Birds – May ambush ground-dwelling or roosting birds.
- Reptiles – Possibly hunts lizards and small snakes.
- Insects – May supplement its diet with larger arthropods in times of food scarcity.
Its long tail and agile build suggest it may be partially arboreal, using trees to stalk prey or escape threats. However, there has been no direct observation of its hunting behavior, leaving its exact feeding strategies a mystery.
What Eats Bay Cats? – Predators & Natural Enemies
Because of its reclusive nature, there is very little recorded data on its predators. However, it is likely that the clouded leopard (Neofelis diardi), Borneo’s apex predator, poses the greatest threat to bay cats, especially juveniles. Other possible predators include:
- Large raptors – Birds of prey such as eagles could target young bay cats.
- Pythons – Large snakes may ambush unsuspecting individuals.
- Civets or other carnivorous mammals – Potential competition for food sources.
As with many small felines, its best defense is its elusiveness. The bay cat’s preference for dense forests and remote regions helps it avoid encounters with potential threats.
Behavior & Lifestyle
The bay cat is one of the least observed wildcats, and much of what we know comes from rare sightings and camera trap footage. It is believed to be solitary and territorial, marking its home range with scent markings and scratches. Most evidence suggests that it is nocturnal or crepuscular, being most active at night or during dawn and dusk.
Some reports suggest that it is a skilled climber, possibly using trees as both hunting grounds and escape routes. Unlike larger cats, it likely relies on stealth and ambush tactics to capture prey. Given its secretive and highly elusive nature, further research is necessary to understand its full range of behaviors.
How Do Bay Cats Reproduce?
Reproductive behaviors of the bay cat remain unknown. Unlike other small wildcats, there has been no direct observation of their mating habits, gestation period, or parental care. However, based on closely related species, scientists estimate that:
- Kittens are dependent on their mother for several months, learning essential survival skills before becoming independent.
- Mating may occur year-round, with peaks in reproductive activity aligning with prey availability.
- Gestation likely lasts 70 to 78 days.
- Litter size is probably 1 to 3 kittens, similar to other small wildcats.
Are Bay Cats Endangered? – Conservation Status & Threats
Yes, the bay cat is currently classified as Endangered by the IUCN Red List, with a declining population primarily due to habitat loss. Major threats include:
- Deforestation – Borneo’s forests are disappearing at alarming rates due to logging and land conversion for oil palm plantations.
- Habitat fragmentation – Roads and settlements further isolate bay cat populations, limiting breeding opportunities.
- Poaching & Illegal Wildlife Trade – Though not heavily targeted, some bay cats have been caught and sold illegally.
- Lack of Research – The absence of data on population size, reproductive habits, and behavior makes conservation efforts difficult.
Efforts to protect the bay cat include:
- Habitat preservation – Conservation areas and national parks provide safe refuges.
- Anti-poaching laws – Stricter enforcement against illegal hunting and trade.
- Camera trap monitoring – Ongoing research aims to collect more data on bay cat populations.
- Community engagement – Educating local populations about the importance of wildlife conservation.
Despite these efforts, more research is needed to effectively protect this mysterious feline. The bay cat remains one of the most elusive and poorly understood wildcats, making it both a symbol of Borneo’s rich biodiversity and a challenge for conservationists.
