Pet Age Calculator: How Old Is Your Dog or Cat in Human Years?
Pets age differently from humans, and knowing their “true age” helps owners provide the right care at every stage of life. For example:
- A 1-year-old cat is like a teenager at 15 in human years.
- A 7-year-old dog may be middle-aged or senior depending on breed size.
Understanding your pet’s age ensures timely vet checkups, proper nutrition, and lifestyle adjustments.
How the Pet Age Calculator Works
Our Pet Age Calculator uses formulas based on veterinary research:
Dogs: Age varies by breed size
- Small dogs live longer and age more slowly.
- Large breeds age faster and reach senior status earlier.
Cats: Cats age quickly in the first 2 years, then about 4 human years for every cat year after that.
