Cat Age Chart: Cat Years to Human Years

How Old Is Your Cat in Human Years?

September 9, 2021

How old is your cat in human years? Consult our Cat Age Chart, which converts cat years to human years. Are you surprised at your cat’s “human” age?

The old “seven year” rule is simple but not quite accurate because cats age more rapidly during the first two years of life. In a feline’s very first year, he or she reaches the human age equivalent of 15. By a feline’s second year, he or she is the equivalent of age 24. 

Cat Age Calculator: Cat Years to Human Years

If we think like a cat, here’s how a cat’s age compares to a human’s age. Of course, there are some differences in age conversion, depending on breed, weight, and other factors, but this chart gives you a general idea.

How to Figure Out Your Cat’s Age

If a cat is adopted or a stray, you may need to use other clues to estimate the age of your feline friend. Below are a few general guidelines, but these characteristics will vary between cats, depending on health, previous care, and circumstances. For best advice, consult a veterinarian.

  • A cat’s teeth: In general, the older the cat, the more stained the teeth. White teeth means that the cat is probably younger than 1 year. If there is some yellowing, the cat might be between 1 and 2 years. Tarter build-up on all the teeth may translate to age 3 to 5, but keep in mind that certain cats are more prone to tartar build-up than others; certain diets may promote tartar; and the lack of tartar may just be an indication of previous dental care. Missing teeth may mean that the cat is senior, although health issues and other causes (such as previous dental surgeries) may also result in the loss of teeth.
  • A cat’s coat: The older the cat, usually the thicker and coarser the fur. (Keep in mind that different breeds/mixes will have different coat thicknesses, and may naturally have fine or thick fur at any age.) Senior cats may have patches of white or gray.
  • A cat’s muscle tone: Younger cats are muscular and older cats often are bonier with extra skin; as they age, their shoulder bones may protrude more.
  • A cat’s eyes: Young cats have very bright, clear eyes, usually without any discharge, depending on health and breed. As the cat ages, the cat’s irises may appear jagged. A cat with eye cloudiness may indicate a senior, but there are health conditions, some of which require immediate care, that also can cause cloudiness. (If you kitty’s eyes are cloudy or watery, or if she is squinting often, consult a veterinarian as soon as possible. Certain eye conditions can get worse quickly, and cause more discomfort, if not treated soon.)

Noire is 16 years going on 17

Noire is 16 years going on 17 months. She's adorkable, forever young and whenever I offer her food she says she's stuffed.

I think being plush helps keep her young.

Maybe waiting for the end

Fuzzy is 17 and will be 18 in September if he makes it. It started out as allergies and by today he has not eating in three days. He is still drinking water occasionally during the day. I had gotten a visit with the vet in a week, but I've already emailed them to see if anyone can see him tomorrow. His breathing at times is terrible and I can feel is rib cage and spinal cord in detail.

Fuzzy and his sister Ana were rescued from a field in Iowa when they were two weeks old. Both were bottle fed until they could be adopted out. I took over their care when they were two because my brother had to move for a job. Ana died last June very quickly. And I think Fuzzy may be ready to go join her and wait for me later. The stories here warmed my heart. I'll miss him dearly if I have to make that decision, but I'd rather stop his suffering than be selfish and keep him around longer than I should.


I adopted a lost cat Daisy in 2009 when she was 1 1/2 years old. In 2011, She had to get surgery on her paw due to an infection, Daisy was a good cat until her death in Jan 2021 due to heart disease, Daisy I miss you soooo much. Rest In Peace My Sweet Angel.

How to know if your cat is blind

How to know if your cat is blind is if it bumps in to a lot of things and falls done a lot.

You may wish to test your cat’s reaction. Move a fingertip quickly towards your cat’s eye and see if it flinches. Try dropping a ball of yarn in front of your cat and see if you cat watches the ball’s motion.

My duby

My first cat as an adult was a scrawny black and white female. Boy, did she ever have a strong personality! But she was smart and trained easily. She slept in an Easter basket with a towel in it. On the kitchen bar. I carry a lot of guilt because I was sick when she became ill and couldn't give her what she needed, comfort. I was able to get her help, but it was too late and I had to put her down. I cannot forget the look in her eyes before she passed. It's been seven years. I will love her forever.


Pandora age 16 died 3 weeks ago after being sick for 2 months. She was my companion and slep with me for 11years. We shared a lot of happy time and some not so happy times. I still hurt from missing her. After she died her spirit came back to show me she was alive and well. She stayed for 4 days when I was so lost in my grief at her passing. On the 4th day I told her i loved her and if she needed to move on I would understand if she couldn’t stay. Before that I could see her very clearly but after telling her that the next day her image was a ghostly shadow. I know she is waiting for me and that one day I will be with her again.

23/113 Cat

She is a Siamese Maine Coon. Every winter she would lick and rip I try and help and snip a little bit with the really sharp scissors and all winter we just take off her summer battle coat.
She would deliberately roll around and get her for all matted up so when she was protecting her dad nothing would get through her thick battle coat cats couldn't get their claws through her coat or teeth. People ask how ?what did I do to help her live so long.

Great Article

Interesting article. Thank you very much for sharing!

My Loves

I had to put down 2 of my Kitties last year, one was 19 and the other was 14. BooBear was a grumpy old man, but at 92 who could blame him, he was failing and going potty around the house. Lost a ton of weight and threw up a lot. Buddy was 72, I raised him from kittenhood. He got cancer that a prev vet failed to biopsy a black spot on him. No matter how much I miss them, I know they are waiting for me at the rainbow bridge and we will cross together, until then they are in the meadow playing with the others who are waiting for their human companions. People never understand how painful it is to lose a pet when they become not only a part of your family but like one of your children, you are bonded. Don't let people get you down. Just know there other pet-parents who understand how tender your heart is after a loss. My heart and prayers are with you and your guardian pet angel.

Update the chart

My cat is turning 26 in a week from when he was born. How old will he be. 120?

Big Girl is 25

My oldest cat is still kicking at an assumed 25. We rescued her as a feral stray that was hanging around a friend's barn almost 23 years ago, and at the time our vet guessed she was approximately two. She had been a homebody indoor/outdoor cat most of her life, by that I mean she didn't go far if she went outside, but eventually she stopped showing any interest in the outdoors, and hasn't left the house in about six years now.
She pretty much lives her life in our bedroom, we got her some pet stairs so she can get into the bed without climbing ( her jumping days are long gone) and still follows me downstairs every morning for a few Kittie treats


I bought a pedigree rag doll in she celebrated reaching 11.....not that amazing for a cat to reach that age, but not long after I bought her she started to have seizures, she went through lots to still be here, and has been on medication twice a day since then, costly to me, but it’s kept her alive, no seizures for 14 months, that does not mean they have gone away, we have been at this point before and then she had one, the medication reduces the intensity. She is truly loved and cherished, and a
mummy’s girl....where I am she is.....Happy 11th my beautiful Blue.......didn’t think we would see this one

My best friend Ever

Omg I’m in tears as I read other people’s posts and Sadly I lost my best friend ever he was my buddy and pal for 19 1/2 Precious years and I truly believe he absolutely understood English as I’d always tell him that me how awesome he was and he fought so hard the week we shared as I also understood he wasn’t ready to say goodbye because he literally followed me and never left my side even though I knew he knew that final goodbye was coming and call me crazy or what but his final night I stayed awake and I told him that it was okay to let go because daddy loves you and will always love you and that I’ll not be mad and that someday I’ll see you again and that’s a Promise!! Omg the tears are flowing..His name was Shaddow... I really just felt a need to share this and maybe it’s a way for myself to heal which at this point seems like I never will because it’s still so fresh and to be honest I don’t think time can truly heal the loss of a best friend, buddy or family member ever!! Thank y’all for giving me a place to share about my best friend Shaddow!!! I Love You Buddy and until we meet again ❤️❤️

26 years old

I have a cat we rescued at a gas station when she was about 4 weeks old ,she just turned 26 in Sept.2019, She has lost teeth,claws ,and much skin hangs down she has what I call senior moments and eats very good some days other days not so good. Vet said she had congestive heart failure 4 years ago He is shocked when ever he sees her ,says she is in good health for her age He tells her I think your going to out live us all.As i bottle feed her when she was found .I would tell her your one lucky girl And Lucky became her name she has outlived 5 dogs and 8 rescue cats.

Poor information

This is poor information. Tartar on the teeth is not an indication of age if they have a poor diet or the opposite if they are getting yearly dental care, nor are missing teeth. It's about their diet and overall health and care. Cloudy eyes? MANY conditions cause that, not just age! This kind of bad information just gives people an excuse to not get veterinary care for the cats and just assume it's age related.

Hi, Bonnie. We understand your concern and have expanded that section to make things clear that, as you say, these indicators are not always ones that imply age but are instead very general guidelines. Thank you for your interest in animal welfare and in The Old Farmer’s Almanac!

Senior kitties

Have 2 furry kids..both calicos. Calli is almost 21 years old, pretty good health, noticeable arthritis but eats like a pig! I have had her since a baby! Beautiful and sweet!

Eloise is a rescue kitty pushing 12 years old. Playful and so loving! She is a rescue, abandoned twice. The last abandonment was in an apartment in Tucson, Az. She was taken by Pima County Animal Control where they discovered she was chipped so returned to the kitty no-kill shelter (PAW-sitively No Kill Cat Shelter)...where they posted her on Facebook. We fell in love and drove from Pine, AZ to Tucson to adopt her after MUCH vetting! So you understand..the ONE WAY mileage to Tucson from Pine is appx. 204 miles...remember that’s one way! Yes, we drove that far to adopt her!

I attribute their longevity to bring INDOOR ONLY kitties...lots of loving care, healthy foods!

Love dogs too...but these two girls are amazing and loved!
