This, here, is a FISHING CAT!

The fishing cat occurs in fragmented populations in the following
southeast Asian countries: India, China, Vietnam, Thailand, Sumatra
and Java. They mainly inhabit areas where there are streams and
rivers of fresh water, usually those covered by reeds, swamps,
mangroves, and marsh.
It somewhat resembles the civet and looks like a housecat too!
(I wonder if it purrs!)

They are very sturdily built animals, very powerful and thick,
strong looking cats. They have a short broad muzzle with virtually
no stop (the point at which the nose meets the forehead); very
small rounded ears set low on the sides of their head; a rounded,
almost pit-bull like jawset; very thick lower jaw and rounded head;
and a thick neck. They have short sturdy legs, a short stubby tail
that is very thick at the base, and their body is very heavy. Their
coloration is a greyish brown with black bars running along their
neck and face, and dark brown spots in rows on their body. Like
most cats, they have eyespots on the back of their ears, which are
black ears with one large white spot in the middle of the back of
each ear. It serves to signal to other felines the cat's mood; the
spots are clearly present when the ears are laid backward so it may
signal aggression. They have a webbing between the toes of their
front paws, and because of this, their front claws cannot be fully
sheathed and so stick out all the time, which probably aid in
catching fish.
As the name implies, the fishing cat is a proficient fisherman and
is never found far from water - however the fishing cat shows a
preference to slow moving or static water sources, swamp margins
and wetlands over faster moving river or stream edges. Observations
have been made of the fishing cat using two distinct techniques
whilst fishing - firstly by taking fish with its paws from the
waters edge and more radically by diving into the water to catch
the fish with its jaws. Naturally the fishing cat is a strong
swimmer. Not all of the fishing cats' prey is water based and its
prey on dry land include rodents, young deer and small wild pig.
The Fishing Cat is also powerful enough to take down calves and
small dogs.
Recent research of the fishing cats diet in
India has revealed that grass also featured as part of the cats
food source. So, it mainly jia hee, jia chai! 
The Fishing Cat is 700-850mm long, weight 6-13kg on average
(females are considerably smaller), and lives for up to 12
years.
Sadly, the Fishing Cat is 'Near Threatened'.
There's a sub-species of the Fishing Cat in Java that's under
'Critical Threat'.
They are often hunted for their fur.
Fishing Cats have proven to do well in suburban habitats though,
and there are people who keep Fishing Cats! http://www.cathouse-fcc.org/fishingcat.html
They seem to be pretty adaptable to human activities, maybe, just
like our housecats!
But I guess that if you do keep one at home, you
ought to get rid of your aquarium first!

Doesn't it look like a dwarf leopard? 

Actually, the first (and only time) I went to the Night Safari, I
was enchanted by the Fishing Cat because it had such an intensity
in its eyes when it was looking at the fishes in the water. It was
so still as it remained mesmerised. Then, suddenly, 'SPLASH!!!' it
jumped into the water without warning, creating a huge splash and
made us all go 'Aaaaaahhh!!!' in total surprise!
hehehe! So pai seh...
, like that, also I screamed!
