Here's why:
* Different Species: Cats (family Felidae) and dogs (family Canidae) are distinct species. They have significant genetic differences that make them unable to interbreed and produce fertile offspring.
* Evolutionary History: Cats and dogs diverged from a common ancestor millions of years ago, evolving along separate evolutionary paths.
* Ecological Niches: Cats and dogs occupy different ecological niches, with distinct behaviors, diets, and habitat preferences.
While cats and dogs can coexist peacefully in a domestic setting, they are fundamentally different species with their own unique characteristics.
