Who is to say where this picture was taken other than those who say it is a new creature?
I am not aware of the "viverrid", however I do know that there are some wierd cats here in Djakarta that can be seen walking atop walls and roofs at night, and are said to be a cross between a civet cat and a mongoose.
Two weeks ago, some creature killed all the koi in my fish pond, but did not eat them. They all had gouge marks on their bellies. The catfish were untouched, as were the janitor fish. My missus says it was done by a snake, but I suspect the "viverrid".
