When thinking about a new pet, consider two things: the pet you would like for your home and the pet that would most appreciate your hospitality. Those cute kittens and puppies will scratch, dig, chew, and wet their way into the house! An older cat or dog will probably start their life with you in a much more respectful manner. Elder pets become homeless in a variety of ways. Sometimes their guardian becomes ill or passes away, and the extended family doesn't want the animal. Other times, frankly, people discard pets as the animals age. Age doesn't necessarily mean that there is anything at all wrong with the pet.
