Feline Life Stages in Human Years

Above, geriatric and young adult—Peaches at age 20 was considered geriatric, and Giuseppe at 18 months a young adult. Giuseppe adored her, and stayed close with her in her last months, escorting her around the house and napping with her to keep her warm.

So just how old is a senior cat, and when do cats go from being kittens to being adults? And are there stages in between, and beyond? And do we count five years for every year to equal the human equivalent, or seven?

While we can generalize over the course of a cat’s life using “7” to multiply to reach a human equivalent, the result is way off the mark at the beginning and end of life. Consider that they can have babies as young as four months old in some circumstances, yet if we multiplied “7” by, say “.5”, we’d get “3.5”. To reach a real human equivalent for the ability to reproduce we’d have to figure it out another way.

For most of the years I’ve lived with cats I’ve had representatives in each age category, but right now my household is a mix of Junior, Prime, Senior and Geriatric—and it’s really hard to think of Mimi as geriatric! And actually, Mimi and her kids are all older than me in human equivalent years. Nearly all my cats lived to their geriatric years. It’s a good indicator of where they are and what they need.

And if you’re wondering about adopting an older kitty, this may help you understand where they are in their lifespan.
