Cats don’t receive mail from AARP, retirement centers or medicare.  Somewhere between the ages 7 and 12, they begin to show that they’re aging. As with humans, age is all relative. The old notion that one cat year is equal to 7 of ours is not reliable at all. A one year old cat is similar to a teenager.  A two year old cat is about 21 in human years. Each following cat year equal about 4 human years.  To reverse comparison, a 52 year old person is similar time wise to a 10 year old cat. A 65 year old person is about 13 in cat years.  You could say that 73 is the new 15 in cat years. How many cat years are you? Don’t  ask your cat, he’ll just meow to tell you it’s time for his cat treats!
