Behaviorally, cats are often more solitary and can spend considerable time alone without feeling lonely. Dogs are pack animals by nature, often seeking constant companionship and requiring more attention and social interaction.

Cats usually require less training and are more self-sufficient, often using a litter box for their needs. Dogs, however, require more training for socialization and obedience, and need regular walks for exercise and toileting.

In terms of communication, cats often use purring and meowing to express themselves, while dogs bark, whine, or howl. Each has a unique way of interacting with their environment and their human companions.

Cat
Any animal belonging to the natural family Felidae, and in particular to the various species of the genera Felis, Panthera, and Lynx. The domestic cat is Felis domestica. The European wild cat (Felis catus) is much larger than the domestic cat. In the United States the name wild cat is commonly applied to the bay lynx (Lynx rufus). The larger felines, such as the lion, tiger, leopard, and cougar, are often referred to as cats, and sometimes as big cats. See Wild cat, and Tiger cat.
Laying aside their often rancorous debate over how best to preserve the Florida panther, state and federal wildlife officials, environmentalists, and independent scientists endorsed the proposal, and in 1995 the eight cats [female Texas cougars] were brought from Texas and released. . . . Uprooted from the arid hills of West Texas, three of the imports have died, but the remaining five adapted to swamp life and have each given birth to at least one litter of kittens.
