Apparently this animal was photographed in south-eastern Yemen where it was frequenting a building site. The photos were taken by Jim Larsen. He reported that the cat wasn't just hanging around the site, it was also chewing on cables; so much so that they had to take measures to stop the cables getting damaged further....
What is this animal? Of the cat species that occur at the southern end of the Arabian Peninsula, it lacks the striping characteristic of the African wild cat Felis lybica, and of course looks nothing at all like a Sand cat F. margarita. Apparently there's been some suggestion that it might be a Caracal Caracal caracal, but it doesn't look much like one at all. In fact, if its fat, rounded face and bob-tail are natural features it doesn't match any known species.
I am convinced that there are a large number of strange creatures out there that we haven't encountered yet. It's a big planet.
