Felidae

 Felidae is the biological family that includes cats, both wild and domestic. This family is part of the Carnivora order and is characterized by a range of features that make them efficient predators. Felidae includes well-known species such as:

1. **Big Cats**:

   - **Lions** (Panthera leo)

   - **Tigers** (Panthera tigris)

   - **Leopards** (Panthera pardus)

   - **Jaguars** (Panthera onca)

   - **Cheetahs** (Acinonyx jubatus)

2. **Smaller Wild Cats**:

   - **Cougars** (Puma concolor)

   - **Lynxes** (Lynx species)

   - **Servals** (Leptailurus serval)

   - **Caracals** (Caracal caracal)

3. **Domestic Cats** (Felis catus): Descended from wildcat species, domestic cats are also part of the Felidae family.

Felids share common traits like retractable claws, sharp teeth, keen vision, and a powerful hunting instinct. They are spread across the world in a variety of habitats, from rainforests to savannas, deserts, and even urban areas (for domestic cats). The family plays a crucial role in ecosystems, often acting as apex predators.
