Caturday Special: Fishing Cat (Prionailurus viverrinus)

The Fishing Cat (Prionailurus viverrinus) is a beautiful, muscular cat, built for swimming and with a teddy-bear like round head with little rounded, back-set ears that make it look permanently shocked by something! HUG IT! (Credit: Kelinahandbasket CC-BY-2.0)

The fishing cat (Prionailurus viverrinus) is probably the first cat since the Pallas cat that we have covered that looks like a teddy bear. These things are so damn adorable looking. They do not have a typical feline headshape, instead they have these little tucked-back ears on a little round head that makes it look like the kind of animal you just want to hug.

They’re another of Asia’s wildcats and as their name would suggest they are pretty at home around water. Wetlands, rivers, lakes and mangroves are all places this little kitty calls home with populations mainly in Sri Lanka, India and Bangladesh, although it ranges down into Southeast Asia too. This disconnection, the fragmentation in its habitat, as well as exploitation of, and decline in its preferred wetland habitats have made this cat vulnerable. They are also subject to persecution where wetlands, rivers or lakes are converted to aquaculture, fish-farming and the like.

It is honestly sad to read about, knowing this is a vulnerable species we might be talking hundreds of animals a year dying due to human-related causes, whether that be exploitation, persecution, over-fishing reducing their prey species etc.

The distribution of the fishing cat based upon IUCN data from 2016. As you can see its distribution is what is known as ‘fragmented’, it has lots of small, unconnected populations. The reason this is a concern is it prevents gene-flow, shagging between the populations, preventing inbreeding and encouraging genetic diversity. One of the key conversation aims should be to link up some of these populations with safe ‘corridors’. (Credit: BhagyaMani CC-BY-SA 4.0)

I’ve been having lots of discussion recently about living with, not against, nature, especially after my Top Ten Hated (But Misunderstood) Animals series of articles. There is a lot we humans do to wall ourselves from the intrusion of the natural, there is a lot of ruin we do to keep our habitat pristine but at the expense of everything else. We disconnect ourselves from species that cannot live with us and feel uncomfortable with those that can. This little cat here is a perfect example.

This is no tiger, it’s no tiddler, but it’s no tiger either. I wouldn’t even call it a medium-sized cat. It is the largest known of all ‘small cat’ species. It is around 60-70cm head to body, with a short tail (Feline Pop-Quiz: What would it having a shorter tail suggest about its lifestyle?) of maybe 20-30cm, so It’s about 80-100cm total length, maybe 30-40cm shoulder height. We’re talking about twice the size of a domestic cat, with females at the dramatically lower end of the size scale (hitting around 6kg, whilst males can be up to 16kg). My sister’s cat, Bob, we’ve seen him before, is anywhere from 7-9kg depending on season and whether he’s been sneaking food elsewhere!

Awwwww! How can you not love a cat that loves to swim. There’s something about cats swimming that just toasts my heart with love. (Credit: blende12 via Pixabay)

They have shortish fur that can range from yellow to grey, with characteristic stripes moving backwards from the face and becoming spottier as it moves back until it becomes a banded pattern at the tail. This fur is, like other aquatic or semi-aquatic animals, layered to provide insulation. They have a short layer and a longer layer of guard hairs.

Then we have the ears! Such cute little ears! Rounded more than pointed and set low and backwards so it looks like the cat is permanently spooked by something! It’s adorable.

An excellent look at the pelage, the coat or fur, of the fishing cat. You can see how the stripes become spotty past the shoulders, forming stripes again near the rump and then the banded tail. Also, bonus points for mlem! (Credit: blende12 via Pixabay)

Let’s answer the Pop-Quiz question? A shorter tail would suggest this cat does not heavily rely on balance to hunt, so it’s likely not a very arboreal (tree based) hunter (like the clouded leopard which has a very long tail) or a sprint hunter like the cheetah (also has quite a long tail). It’s not a bob-tail, though, so they can’t do without it, crawling along the branches in mangroves clearly requires some counterweight.

I asked you to think of that question for a good reason, and I was doing the same thing with my niece at the zoo the other week. There are certain inferences you can make about the lifestyle of an animal by looking at features of their anatomy. This ‘comparative anatomy’ is very important in evolutionary biology and phylogeny (where things go in the tree of life) but I think it’s also an awesome thing for a lay-audience to learn for if they spot something new or different.

KITTEN TAX! This baby, born at the Smithsonian’s National Zoo, shows you the density of their fur pretty well! This is to provide a sort of water-proofing, plus thermal insulation, especially since they are mainly nocturnal hunters they don’t exactly get to dry off in the heat of the sun! But look at this little cutie! (Credit: Smithsonian’s National Zoo CC-BY-NC-ND 2.0)

There are things you can spot, e.g. it’s got a long tail, which can combine with other things, e.g. it’s got a greenish-grey colour with spots or stripes, that you can combine with even more features, e.g. it’s got relatively long, sharp teeth – and it all comes together into “This is a tree-dwelling or hunting carnivore species, it is camouflaged for life in vegetation, the long tail suggests it requires balance and the teeth suggest it eats other animals.”

The common genet, Genetta genetta, we’ve come across these before in our article about Feliformia, the cat-like carnivores. Why is it here? Well, notice how it has a long tail? Dusky spotted or striped coat? Look at those big ears, as well, all the better for hearing small prey like insects or small rodents. I bet if we had a look in its mouth it’s got sharp teeth! … “This is a tree-dwelling or hunting carnivore species, it is camouflaged for life in vegetation, the long tail suggests it requires balance and the teeth suggest it eats other animals“!

You might be wrong! But this is part and parcel of any science, learning the ‘heuristics’ – the rules of thumb – to make inferences or predictions and then using observations and evidence to see if you are correct.

Common names are also quite useful for this. What do you reckon the ‘fishing cat’ eats?

If you guessed ‘fish’, you’re approximately 75% correct! Analysis of their poo in India suggests around three quarters of their diet is made up of fish, with molluscs, small reptiles, rodents, birds and insects making up most of the rest.

They are, unlike most feline species, strong swimmers and very comfortable in the water, even swimming underwater. They are believed to be mostly nocturnal and they have been seen hunting both at the sides of water, fishing almost as a domestic cat would at a pond, but also diving into the water to nab their fish.

Across much of Asia, in multiple different languages, this cat is named some variation of ‘fish tiger’. That’s awesome! It’s a cute little cat, but sadly human exploitation and conflict have put it in very real danger. Even with plans in place, even with protection orders across much of its habitat, many cats will die due to unnatural causes, mainly human. A study in Thailand that was radio-collaring the cats found 84% of them died due to poaching or ‘unknown causes’. They are prone to trapping, poisoning and snaring, too.

I always hate having to be so negative near the end of an article but to me it’s like someone killing their pet cat because they paw at the dinner on their plate, you know? These human/wildlife conflicts so often seem to come down to that. I get it, these areas of Asia aren’t exactly bursting with millionaires and these cats can probably come in and snatch several fish per evening. At the same time there are ways to peacefully co-exist, even to turn the fishing cat into an ally. Sadly for many of these people taking time, energy, money to learn how to co-exist with these cats is seldom an option.

Nothing to see here, just the incredibly boopable schnoot of a sleepy fishing cat that looks like it is smiling because its happy to just be a cat. (Credit: Wildfaces via Pixabay)

It’s a tough problem. This is not like with tigers where I can be outright angry because poaching is the lazy way to make money off of them, because programmes and tourism schemes have shown demonstrably that wild tigers are bank, the promotion of wild tigers is in the financial interest of the communities who coexist with them. Are people going to invest in wildlife tourism to watch a fishing cat hunt? I would but I’m not ‘most people’ – I’m a feline freak!

There are charities and NGOs working right now in various areas to save this cat. To ensure its protection by finding ways to work with locals to slow conversion or habitat and create schemes where local communities can earn money with alternative means so they do not have to damage the habitats of these gorgeous wild cats, or directly persecute the cats themselves due to conflict.

Hopefully we see the fruits of these labours paying off in the coming decades, and fishing cats can find a comfortable, welcoming home by the rivers, lakes and mangroves of Asia.
