There is a world somewhere between reality and fiction. Although ignored by many, it is very real and so are those living in it. This forum is about the natural world. Here, wild animals will be heard and respected. The forum offers a glimpse into an unknown world as well as a room with a view on the present and the future. Anyone able to speak on behalf of those living in the emerald forest and the deep blue sea is invited to join.
Well, this question is hard. If we see the current scenario, I consider Leopard is the best candidate for survival almost in all condition. So far they have shown versatile survival skills which are better than others.
But if we see the history of mass extinction, animals with low profile manage to survive and had become dominant with a lot of changes in them related to behaviour, size, shape, and other physical parameters. Animals which hide most of the times, catch and eat anything, even small prey like mice and rodent will have better chance. So in my opinion small cats like clouded leopard, Lynx, Bobcat, Caracal, Serval, Leopard cat, Fishing cat, Ocelot, etc will be able to survive and do much better than current big cats.
