The fight to save India's most elusive cat

The encounter took place on a cool winter morning in 2012, in the coastal Indian city of Visakhapatnam. A gentle breeze nipped at the air as Murthy Kantimahanti stood transfixed, staring at a metal trap set up on a dirt trail leading to dense bushes and towering neem trees. Inside the trap was a cat – but no ordinary cat. It was bigger than a house cat, but not as big as a leopard or a tiger. It had a squarish face, relatively small ears for the size of its head, a short tail and curiously webbed feet, like an aquatic animal.

Kantimahanti had just arrived at the Indira Gandhi Zoological Park in the heart of the Seethakonda Reserve Forest, where he worked as a biologist. He was used to seeing native wildlife like Sambar deer, the Asiatic wild dog, the Indian leopard and gaur (also known as Indian bison) ranging within the park's natural enclosures, bordered with hedges and trenches. But this cat was something else entirely.

Kantimahanti's area of research was cataloguing the behaviour of captive wild dogs in the zoo, located as it was in such proximity to the Eastern Ghats, a biodiverse range of mountains along India's south-eastern coast. It is an area where cashew and mango plantations abound. The zoo often baited traps to catch feral dogs and he would monitor their behaviour. On that winter morning, he had received a frantic call from a colleague at the zoo, summoning him to a particular cage by the dirt trail.

“I was fascinated, " he says. “The zoo had laid a trap with beef in it to catch a feral dog. Quite astonishingly, a cat had grabbed at the beef instead, and was ensnared. "

The zoo authorities were puzzled by the animal's webbed feet and strange appearance. This seemed to be no ordinary cat.

Kantimahanti recognised the animal at once. To the trained eye, a fishing cat 's appearance is distinctive, but if ever there was any doubt, there was one trait that helped Kantimahanti identify it instantly –  sheer aggression. Having eaten its piece of beef, this cat, a male, lunged fiercely and repeatedly at the bars of the trap.

"If you ask researchers who study the behaviour of fishing cats in the wild, they will tell you that it never backs off, " Kantimahanti says. "Even when they see a human being, they stand their ground. "

The cat was tranquilised, treated for bruises, and released back into the wild. It was the first documented sighting of a fishing cat in coastal Visakhapatnam. 

Until then, fishing cats had only ever been sighted in the state's Coringa Wildlife sanctuary, known for its extensive mangrove forests, four hours away. Very little was known about the fishing cat 's behaviour, despite it being found in 11 countries across Asia. 

The encounter helped state authorities realise that fishing cats were a natural part of Andhra Pradesh's wetland landscape and far more widespread than they’d previously assumed. It sparked one of India's first fishing cat surveys, carried out between 2014 and 2018. Kantimahanti, who went on to found the conservation organisation the Eastern Ghats Wildlife Society, has been working to understand the fishing cat's behaviour ever since.

The first challenge was to find out how widespread the cat was. Researchers from the Wildlife Institute of India began an arduous scanning of the Coringa wildlife sanctuary as part of the United Nations Development Programme project to document the biodiversity in the region. In 2015, the Krishna Wildlife sanctury, 150 kms (93 miles) south of Coringa was surveyed by the Eastern Ghats Wildlife Society and the Andhra Pradesh Forest Department. Camera traps from the survey revealed the presence of 10 individual fishing cats amidst the vast tracts of tidal mangrove forests, though a population estimate for these elusive cats – which relies on clearly identifying an individual cat's distinctive markings – evaded them.

Besides numbers, the census revealed some of the idiosyncrasies of this elusive cat. The survey identified the first known inland fishing cat, found in freshwater habitats along Srikakulam district in northern Andhra Pradesh. Then in December 2020, Kantimahanti was startled to see camera-trap footage of a cat hunting a freshwater non-venomous snake. Fish had been considered the cats' mainstay, and the cats were only thought to prey on other animals when there was a dearth of fish – though on this occasion there was plenty of fish available. In another incident, villagers had assumed a large cat attacking their livestock was a leopard, but it turned out to be a fishing cat. Another camera feed showed a fishing cat being run over by a train while chasing goats.

“The name fishing cat is a misnomer," says Kantimahanti. The cat is a markedly versatile predator. "It can hunt animals bigger than itself, survive anywhere, feed on anything."

Today, growing awareness of the fishing cat in India has sparked a monumental journey towards conservation. Researchers on the trail of this elusive jungle feline are mapping its habits and habitats across the country and studying pollution, human and environmental threats that harm it. They're documenting its effects on climate change and through litigation, using wildlife laws to protect its terrain.  

All this, because woven into the story of fishing cats, is that of the wetland habitat itself.

Counting cats

India is home to a rich wetland territory, occupying nearly 5% of its terrain. The Sundarbans in the north-eastern state of West Bengal is the country's most well-known wetland habitat, stretching over 4,230 square kilometres (1,633 sq miles). A total of 42 sites across the country are considered wetlands of international importance due to their biodiversity, according to the Ramsar Convention, an international agreement on wetland conservation.

The fishing cat is usually found in two types of habitat within a wetland: mangroves and marshes. They take refuge in the reed fields – the long-bladed wetland grasses that grow in swamps. "They prefer shallow wetlands and are nest-making cats," says Tiasa Adhya, a Kolkata-based conservationist and co-founder of The Fishing Cat Project. Their nests, made with marshy reeds and secluded in the tree holes of mangroves, are why the habitat is so inseparable from the species. "It's here, where you can find a rich haul of snake-head and cat-fish, on which the fishing cat thrives," says Adhya.

Predators like wolves are known to shape the landscape in which they live through their predation, but the extent to which the fishing cat influences the nature of the wetlands remains unknown. What is clear, is that a healthy population of fishing cats means a healthy environment to sustain them.

In one these wetlands, at Chilika Lake in the north-eastern state of Odisha, India's first census for fishing cats outside of its protected reserve forest areas is now underway, in collaboration with the Chilika Development Authority, a government agency. "Fishing cats inhabit the extensive deltas and flood plains of river systems, the shallow wetlands connected to rivers in South and South East Asia," she says. 

Being a nocturnal animal, they are more likely to be caught on camera traps than by eye during the day. Over a hundred camera traps are to be left in Chilika lake for 30 days. They're focusing more on the freshwater dominant areas of the lake, says Adhya, setting up the cameras in areas where they've spotted pawprints, or pugmarks. Setting up one camera trap can take up to two hours, and Adhya's team has recruited local people to help and put out word among the 200,000 strong fishing community in the area so that the camera traps remain undisturbed.

This census is up against the same challenges as the first surveys of fishing cat numbers. Estimating the population of fishing cats is tricky as it relies on getting a clear picture of the cat to analyse its subtle but distinctive body marks, made up of spots, stripes and patches.

Growing threats

Adhya has been observing fishing cats since 2010, ever since she chanced upon its pugmark in the wild as a researcher in the Sunderbans. The footprint intrigued her; it was roughly the size of a dog 's paw, but smaller than that of a tiger's. She learnt that fishing cats were integral to wetlands, but there was little awareness about them, even amidst local communities. And in recent years, researchers have noted several threats.

The first comes from humans: wetlands directly and indirectly support hundreds of thousands of people, providing livelihoods to fisherfolk, indigenous communities and farmers. There are inevitably moments of conflict. Retaliatory killings of fishing cats spurred by human conflict were well known in West Bengal. Adhya launched awareness campaigns and enlisted the help of locals to prevent poachers from hunting fishing cats for meat, which was being sold in local markets. Over the years, she says these efforts have helped mitigate conflict. "While there are still road kills, the retaliatory killing of fishing cats has significantly reduced," she says.

If fishing cats are to have a home alongside humans in a rapidly developing world, this ingenuity could prove essential to its survival.
