If you looking a way to convert cat years to human years so you will know how mature your cat condition really is. Actually there are people that said that for a cat one year, it is equal to seven years in human.
However, as you can see, a one year old cat is much more matured compared to a seven years old human. Thus this theory might not be true after all.
Things That affect Cat Years to Human Years
Actually there is no known scientific method known to convert animal years to human years including for the cats.
The reason is because the cat maturity growth is actually worked in different timeline compared to human maturity growth. But even with that, you can try to understand more about your cat maturity which you can try to compare to human maturity.
Actually cat only spend little time in their lives in immature stage. That is why; it is quite hard to compare their year to human year. A cat will grows faster in their first two years of living, and then a cat will have slower growth rate afterwards.
You can understand this easily by knowing that a cat is already sexually as well as physically developed within the first year in their lives.
However, for human we will reach similar maturity at least when human are fifteen years old. Thus if you compared those two, then you can say that the first year in your cat lives equal to fifteen years in human lives.
But it will become even more complicated in the cat second year. In this year, your cat maturity level is similar to human when they are 25 years old.
This make the cat only grow around 10 years in human year. This number comes from 25 years minus 15 years in the cat first year, thus your cat only grows 10 years in their second year.
Then after reaching this year, then their growth will become slower, thus it will be easier to count them. On this stage the cat third year development and onward is similar with human four year development. Thus one year of their lives will equal with four year in human lives.
Knowing all of this information will make it easier for you to empathize more with her. Thus you will know how to treat her when she already more mature. And you will also know how regular the veterinary checkup should be done.
