It seems to be a juvenile civet cat or Urulaawa in Sinhala.
Thanks Bushana. It is a surprise to see these animals around a city like Hikkaduwa.
It seems to be very cute.
But be careful on bite or scratch by such animals.
They might infected with rabies
Since you have no facilities to observe the animal, be extra careful on handling such a situation next time.
Thanks a lot Viraj, I couldn't let the animal to be eaten by the dogs.
