How Old Is Your Cat, Really? Find Out With The Cat Age Calculator #ad #HillsPet

Cat Age Calculator From Science Diet ~

Science Diet Most Interesting Cat and Cat Age CalculatorCheap Is The New Classy

I know that we have all heard that 1 year for a person is 7 years for a dog. But what about cats? If you are wondering about how old your feline fur baby is as compared to a human, look no further. Science Diet has come up with a cat age calculator that they have kindly allowed me to share with you as well as some advice to help you take care of your aging cat’s special dietary needs.

Cat Age Calculator

Thanks to modern medicine and smarter lifestyle choices, people are living longer. Cat age is increasing as well at a rate of 6%.

  • A cat that is 7-10 years old is considered a “mature adult.” Although we adopted our funny cat Garfield, I think he was about 10 or 11 when he passed away. Most of the cats that we own own us now are younger, so we want to start them out with a better nutritional advantage so that we can hopefully have lots of fun years together. :)
  • Cats that are over 11 are considered senior cats.

How Older Cats Differ From Younger Cats

Older cats may exhibit lots of differences from younger cats. For instance, older cats may change the way they “talk” to us or change the way they use their little box. When you are choosing how to take care of your old cat in the food department, you really want to concentrate on longevity, overall life improvement and decreasing the risk of chronic and potentially life threatening diseases that affect the major organs. You also want to choose food that promotes good oral health.

  1. I love science diet pet food. When my baby girl was sick last year we had to switch her to a prescription version of it. Sadly it was a bit too late and we lost her but the dog food definitely made a difference for a bit.

  2. I had no idea that cats age differently, just like dogs do. When we still had our cat, we had to feed him a special diet, too.

  3. This is some really great information, I know a lot of pet owners who just purchase whatever is the cheapest and they don’t really care what it is. The shelter we adopted our cat from gives a bag of Hill’s to everyone who adopts!

  4. My mother in law is a cat lover. So I will send this to her! Thanks!

  5. I have often heard people talk about dog years, but never cat years. This is a new and interesting concept for me.

  6. Great post! I never knew age was a factor for foods!

  7. We don’t have any pets for now since our kids are still very small, but I want to get them eventually. I’ll definitely buy them the best food for their age – it seems like a very important detail.

  8. Ha, ha, ha… totally love this… we used to have cats and science diet was the only way to go. Thanks for your review.

  9. My cat is old and cranky. I adore him. Thanks for the information.

  10. Our family cat lived to be over 20! SHe was so healthy. She spent a lot of time outdoors, not sure if that had anything to do with her living such a long life.

  11. This is good info to know! I have two kitties, one is super old and the other is much younger! It is always important to feed our kitties good food!

  12. I’m not allowed to have a pet. I can’t take care of myself let alone an animal.

  13. Interesting information on cats ages. I never really thought if it was different than a dogs 1yr=7yr.
    We have a young cat and a mature cat than adopted the younger one. The right kind of food makes a difference for each of the cat. thanks

  14. I’m not a cat person, but it is interesting to know how their age is calculated.

  15. I had no idea that cats needed different food at different ages. Great calculator to help determine what is needed.

  16. I had no idea and we are huge cat lovers here.

  17. This is great! Not many people realize that cats (and dogs) become geriatric far sooner than we think, and that they require different nutritional needs.

  18. Good nutrition for animals is just as important as good nutrition for humans!! Science Diet is a great food choice!!

  19. We’ve never tried this cat food before which is a little nuts because I feel like we’ve switched foods up quite often! Our cats drive me completely crazy. But I do love the little fuzzy balls.

  20. I had to smile about the cat age calculator…:-) I don’t have any cats but we have 3 dogs and we only feed them Hill Science Diet and we do notice a difference if we feed them any other food… Been using them for years and won’t switch to anything else; thanks for sharing your Fur babies are too cute

  21. What a pretty cat! I never thought about their age… thanks for sharing the handy calculator!

  22. I thought the cat age comparison was very interesting! I do not own any cats, but your’s sure are cute!

  23. I hadn’t really thought about it but our dietary needs change over time so it makes total sense that a cat’s would too!

  24. I have three cats, so this is a great recommendation!

  25. alicia k (Petite Pilates Pixie) says:

    i like the slider chart to determine the best food. thanks!

  26. We have 2 cats and we try to provide the best diet for them especially since they are older.

  27. I have two cats that are both about 20 years old. I have had them most of their lives. They DO change their habits as they age.

  28. Sherry Compton says:

    Very interesting. I just assumed cats went by the 7 years, too. I’m glad they’ve come out with this information. It is so important to feed you cat the right food. I love how you changed it to “own us.” Isn’t that true. We are always saying we don’t train them they train us.

  29. Candy Cain Severson says:

    My cats are only 3 we think, it’s hard to know because when we got them they told us they were 2 but that was 2 years ago, but they sure changed and from the pictures they looked liked kitties, we think they were mistreated

  30. My oldest cat is almost 21 years old. I think that makes her over 100 in human years.

  31. Linda Szymoniak says:

    I’ve had cats my entire adult life, and am very involved in animal rescue. I’ve learned some interesting things over the years, including the information in this post. One thing many people don’t understand, though, is that indoor-only cats differ from cats that are allowed to roam outside. The indoor cats have an average life expectancy nearly four times that of cats that go outside. There are so many dangers for cats outdoors – cars, dogs, and abusive humans, plus diseases they would otherwise not be exposed to. I have three cats and they are indoor-only. They are also on different diets based on their ages and other issues.

  32. Deborah Caudill says:

    Our older cat who was 20 years old passed away last February. We got her after some horrid teenagers killed her mother and her siblings. She had a broken hip, but the vet said it had already started to heal and he thought she would be okay. We fed her with an eye dropper, but she thrived. We will always miss her. Our baby kitty is 3 and very healthy. Their Hill’s Science food kept them both very healthy.

    • Dawn McAlexander says:

      I am so sorry about what those teens did to the other cats. I am glad you were able to provide a safe home to one of them, though.

  33. lulu is over weitght and she oc coulduse some weight soon

  34. Rebecca Parsons says:

    I love that Science Diet gears their food towards animals of all stages of their lives.

  35. Danielle F. says:

    I am surprised to see that at 7, a cat is considered a ‘mature adult’ since that still seems young to me (maybe time just passes by so quickly w/ a pet) but it’s nice to see that Hills gears their food towards different age groups and tailors the ingredients to that age group’s needs.

  36. I haven’t tried Science Diet on my kitties. I like that they have different food for different ages. I might just have to check it out and see if they like it. Sounds like a great cat food :)

  37. i didn’t realize that cats over 11 were considered “seniors”, i thought it would b older….i currently have cats ranging in age from 3 to 18! My poor 18 year old had her last tooth removed last week and she now sounds like a sheep baaing instead of meowing….thanks!

  38. very interesting and helpful , thank you !

  39. John – Thomas we figure is 21 this year and unfortunately he is showing his age. I’m glad Hill’s has a Science Diet made just for cats like him. He is so special. My oldest Son is also 21 and they grew up together and we want to keep John Thomas as healthy as possible.

  40. I had a cat whom lived for 18 years, it is so different that cats ages go different then dogs.

  41. Well, this really has me thinking. One of my cats is senior no matter how you define it, and it might be time for me to start feeding her food more appropriate for her age. Thanks for this post.

  42. Jennifer Lenhart says:

    My girls are 6, on their way to Mature Adulthood. Their behaviour indicates differently!

  43. this is really cool

  44. I’ve never known a lot about cats other than my son has always had one or two around. This is interesting info. that I never realized! I do know that dogs change when they’re older too.

  45. ellen beck says:

    I have known some cats who lived 20+ and others who fade away much earlier. I think it is much like people with genetics and environmental.
