Animals are multicellular, eukaryotic organisms in the biological kingdom Animalia that consume organic material, breathe oxygen, and are generally capable of movement. They inhabit diverse environments, requiring food, water, shelter, and space to survive. Studies show that pets specifically provide companionship, reduce stress, and improve mental health.

Key aspects of animal life and interaction include:

• Habitats & Survival: Animals require specific habitats to survive, including shelter and resources.
• Physical Characteristics: They are heterotrophs (consume organic material), move, and reproduce sexually.
• Human-Animal Bond: Pets can significantly impact human health by lowering blood pressure and reducing cortisol (a stress-related hormone).
• Behavioral Studies: Research into animal behavior and habitats often covers wildlife and unique species adaptations.
• Conservation & Care: There is an emphasis on compassionate treatment and environmental conservation.
