When people visit the animal shelter, it’s usually the adorable puppies and kittens that get the most attention. An older pet can be a tougher sell. But there is an upside to choosing a more mature companion animal, including being able to tell right away whether your personalities will fit, and the unwavering devotion that is often a hallmark of the rescued senior pet.
