Feline Aging Chart 

Cats usually live longer than most dogs and it is no longer unusual for them to live until 20 or beyond. How long an individual cat will live depends on many factors such as genetics, whether kept indoors or not, type of diet and of course the appropriate veterinary care he/she receives.

The rule of thumb is that at about age 7, a cat is considered to be middle-aged. At age 10 and above, a cat is considered to be a senior citizen but not geriatric until 15 or more years of age.

You can calculate how old your cat is in human years by subtracting one year from your cat's age, multiplying that number by 4, then adding 20.  For instance, if your cat is 12 years old, subtract 1 year = 11 years x 4 = 44 years + 20 = 66 years old in human years.  Or just use the chart below.

    CAT'S AGE                                                 HUMAN AGE EQUIVALENT   

        6 months............................................................................ 10 years

        8 months ........................................................................... 13 years

        10 months ..........................................................................14 years

         1 year  .............................................................................. 15 years

        18 months ..........................................................................20 years

         2 years  ............................................................................ 24 years

         4 years ............................................................................. 32 years

         6 years ............................................................................. 40 years

         7 years ..............................................................................44 years

         8 years ..............................................................................48 years

        10 years .............................................................................56 years

        14 years .............................................................................72 years    

        16 years .............................................................................80 years

        18 years .............................................................................88 years

        20 years .............................................................................96 years

        21 years ...........................................................................100 years

As you can see, a seven year old cat is well into his 'forties'. And since one year for a cat is equivalent to four human years, many changes can take place in what for us, is a fairly short period of time. That is why the American Veterinary Medical Association as well as the American Association of Feline Practitioners recommend twice yearly physical exams plus appropriate blood work on all cats who are 5 years old or above.

For cats over 10 years of age, The Cat Doctor recommends a physical exam every 6 months and a comprehensive set of tests every 12 months that includes:

    *blood profile
    *complete blood count
    *thyroid function test
    *urinalysis

With this program, many health problems which are not readily detected in other ways can be caught early on and appropriate steps taken to ensure continued well-being and a longer life for your cat.
