A cat is a small, domesticated mammal known for its agility and playful behavior. They belong to the family Felidae and are often kept as pets. Cats have sharp retractable claws, keen senses, and a strong hunting instinct, which makes them effective at catching small animals like mice and birds. Cats come in various breeds, colors, and patterns, each with unique characteristics. They are typically independent animals, often enjoying solitary play and exploration. Cats communicate through vocalizations, body language, and purring, which can indicate contentment or other emotions.
