How Old is My Pet
The first year of a pet's life is roughly equivalent to about the first fifteen years for a human and two pet years are equal to about twenty-four human years. After that, each year for a pet is equivalent to four years. This age comparison table provides general age comparisons between dogs and humans.
Cats are considered to be entering their senior years at age seven. The table below provides age comparisons.
As an animal ages many of the normal organ functions gradually begin to decline, just as in humans. The eyes, ears, heart, lungs, liver, and kidneys may start to function less optimally, possibly leading to significant medical problems. It is more difficult for older animals to fight infections and problems such as arthritis frequently set in. It is ideal for senior pets to have their owners and veterinarians work closely together to find and treat problems as early as possible.
