Rayan Sibai:
 * 1) Mammals have sweat glands, mammary glands, hair or fur, and four-chambered heart, and give birth to live young instead of laying eggs
 * 2) Amphibians differ from mammals in that amphibians don’t have hair or fur. In addition, amphibians have a complex life cycle with several stages. Amphibians have an egg stage, larval stage, and an adult stage. Each stage is characteristically different from the other. Mammals on the other hand do not. Amphibians also lay eggs while mammals give birth.
 * 3) Cats are mammals, penguins and parrots are birds, and butterflies are insects.
