How Old is My Pet? Dog and Cat vs Human Years

How old is my pet? Cats and dogs age more rapidly than humans. The rate of this ageing depends on many factors including size and breed. A generalized chart can be found below. The areas highlighted in green indicate a senior aged pet. As they age, pets have different medical and dietary needs. See our specific Senior Health, Puppy and Kitten, and Nutrition links for more details.
