Pets age much faster than humans do

In humans, the senior years are considered to start between 56 and 60 years of age, and regular health screening for age-related disease is usually recommended from 40 years.

Cats and small to medium sized dogs reach middle age at approximately 7 years, while large and giant-breed dogs are regarded middle aged from the age of 5.
