Why are there far more different species of felines than canines?

[Tooting Carmen]

While among canines I can only think of dogs, wolves and foxes (and even they are fairly distantly related), among felines there are lots of different species: domestic cats themselves, lions, tigers, cheetahs, pumas, jaguars, lynxes, leopards... Why is this?

[Annihilus]

Maybe because most cats hunt alone so they are specialized in certain prey whereas canines are mostly pack (social) hunters.

Oh and you also have coyotes.

[Sebastianus Rex]

They are superior predators.

They are superior predators.

So felines have been able to kill off real or imaginary competition more than canines then?

I also forgot about panthers of course!

Cats hunt alone, unlike dogs.
