- Diverse Diet: Although many are strict carnivores, some are omnivorous or primarily herbivorous.
- Social Structure: Ranges from solitary (like most felids) to highly social (like canids).
- Habitat: Found worldwide in nearly every habitat, including forests, grasslands, deserts, mountains, and aquatic environments.
