Servals aren't attractive but they are really exotic. Of course, I don't have one but its high on the list for my dream-menagerie (which ain't happening anytime soon), flirting alongside a peacock and the pretty birds of paradise.
No no ... they have to be friends!

The one I have is descended from others that have been bred by private owners for numerous generations over many decades. It couldn't survive in the wild. And they live more than twice as long as pets.
