Is there a way to tell the age of a cat without going to a vet?

I really have no idea of how to tell the age - their either kittens or old :) Over the years we've had several cats that we didn't have any idea how old they were but didn't matter we just made the day we got or found them their birthday. My cat Indy (Independace) was born on the 4th of July 2006 so know how old she is.

thats ok i know that you like your new cat and i am happy to talk with you about him..How is he doing? has he gotten more friendly? I don't know how to tell the age of the cat..i think how they tell is by looking at the teeth, because i took my animal (also a stray) but this was a long time ago ,and i took it to get shots,and i asked the vet about its age and he started looking in the mouth and at the teeth,but i have no idea what he was looking for or at, but he told me in about what age he was...I also want to tell you this ,because i have 2 cats that you will need to vaccinate him from feline leukemia, because that is a real cat problem, and i also get mine a rabies shot each year..Some people do not think it is b necessary because they are in the house a lot but my vet swears by that...If you look on the internet you can find where they do those vacinations for free at certain times of the year....Cats live a long time i do know that, even longer than dogs i was told...

Cats age differently from humans. They do not live as long, but can be as old as some of our older folks. The formula to calculate a cat's age is as follows: 1. Allow 15 human years for the first year of your cat's life. 2. For the 2nd year, add nine years to its age. So if your cat is two years old, it will approximate 24 human years. 3. Add four human years each for successive years of its life. Following this computation method, the equivalent age in human years for a cat is: Cat Years (equivalent Human Years): 1 (15) 2 (24) 3 (28) 4 (32) 5 (36) 6 (40) 7 (44) 8 (48) 9 (52) 10 (56) 11 (60) 12 (64) 13 (68) 14 (72) 15 (76) 16 (80)

Don't know if he'll let you look in his mouth but his Teeth are about the only way to tell age. I know that if he has his "fangs" as I call them... then he's over 5 months old (but by his height and weight i'd say he's an adult anyhow)....unless you're an expert at teeth, you'll just have to take him to the vets.
