<human>:  Explain the biological differences between cats and dogs.
<bot>: Cats and dogs are two different species that belong to the same biological family, Carnivora. Cats are typically smaller than dogs and have a more slender build. They have wide eyes and typically have a pointed nose and ears. Their fur is usually short and comes in various colors and patterns. Dogs, on the other hand, typically have a broader head and snout and a longer body. They typically have short fur and come in many different colors and patterns. They also have longer muzzles and tend to have a wagging tail like a rudder. Physically, cats are more agile and can jump higher than dogs. They also tend to be much quieter and more solitary creatures. Dogs have a more social nature, with packs being common. They are also more active, often needing a longer time for necessary exercise. In terms of metabolism, cats are less able to process carbohydrates, while dogs do a better job of it. This means cats can sometimes need special diets and prefer to eat smaller meals throughout the day, while dogs will often eat one or two large meals.
