Tiger/Leopard because they're so adorable. A Tigard is the hybrid offspring of a male tiger and a leopardess. Pretty self explanatory. Knowing that we have have Leopons which are the result of breeding a male leopard with a lioness. I think it would be a nice counterpart.

[Taken from Wiki on Panthera hybrid] As it stands there has only been two known attempts to mate, they have produced stillborns or were infertile. However, there have been rare reports of tigresses mating with leopards in the wild. There has even been an account of the sighting of rosettes; the stripes of the tiger being most prominent in the body. The animal was a male measuring a little over eight feet.

Let me know if you agree.
