When you look at the current research on spaying and neutering, the AGE at which it's done turns out to be vitally important to your dog's future health. For example, your female dog should NOT be spayed at 6 months old.
Life Expectancy of Dogs and Cats. We hope our pets will be a part of our lives for many, many years but the fact is that the average life expectancy is 10-12 years for dogs and 10-14 years for cats. Older pets have very specific needs and are particularly susceptible in later years to cancer, arthritis, and dental disease.
On average, indoor cats live 12 to 15 years. A cat may reach the age of 21, if he doesnât have any medical conditions and has a proper diet. The record age for a cat is said to be 36, however, the Guinness World Record is held by a cat in Australia that lived to be 25.
