Cats do not need to be let outdoors to live a happy and healthy life. In fact, they are better off remaining exclusively indoors. They may adapt better to smaller homes or apartments than do some dogs. Cats do not need to be walked, though a cat can learn to walk on a leash. Though their activities can be more solitary, cats thrive on attention and social contact with their owners.
Cats have a very different social nature from dogs.
Cats tend to be more discreet and unassertive than dogs, but they can be as attentive and responsive as any dog. A cat's relatively small size and independent nature make it an attractive candidate for small living quarters and busy households. Males tend to be larger than females and may be more active in general. Females may be easier to train and less destructive. They may not play as roughly as males, but both sexes are equally playful.
