At what age is the cat considered to be an adult?


Little kitten will become big, and very quickly! Indeed, the cat experiences a period of extremely rapid growth and changes dramatically in the weeks following its birth. How does it evolve and when can it be considered an adult?

How long does it take to go from a kitten to an adult cat?

If you have ever had the opportunity to observe the birth of kittens and welcome them into your home from an early age, you will surely remember that these little furballs are born deaf and blind.

Folded ears and closed eyes, the kitten weighs only 60 to 120 grams at birth. Then, its evolution is very fast since in 2 to 3 weeks, its ears unfold and its eyes open. The kitten becomes more agile and begins to walk at 1 month. He no longer crawls and staggers less and less.

At the age of about 2 months, the kitten becomes independent, it eats solid food, it plays, runs, jumps and goes to the litter box. Although he is weaned and no longer needs breast milk, he will not be well socialized until 3 months, time to learn all the social codes relating to his species.

At 6 or 7 months, the kitten has grown well and looks like an adult cat. In human age, this is equivalent to about 10 to 12 years. The kitten then becomes pubescent and is able to reproduce. It is also from this age that sterilization is recommended. If the cat’s growth slows down, it is not over.

Indeed, the cat does not become an adult until between 12 and 18 months, or in human equivalent between 15 and 24 years: his physical, psychological and emotional development is then complete. Note that the growth phase is longer or shorter depending on the breed of the cat. A small size such as the Siamese or the Munchkin will be considered as an adult before a large size such as the Chartreux or the Maine Coon.

Adult cat, what changes for its owner?

Throughout a cat’s life, it is essential to take its age into account by providing it with an appropriate diet. By becoming an adult, the cat becomes sedentary. He exercises less and his physical activity is generally declining. He therefore needs fewer calories.

This observation must of course be qualified according to the individuals and their way of life. Do they have access to the outside or not? Are they sterilized and do they tend to be overweight?

In any case, it is time to adopt a food for junior, adult or sterilized cats from their 12 months. Recalls of vaccines and antiparasitics are also in order.

Your cat’s transition to adulthood is an opportunity to take stock with your veterinarian as part of an annual health check-up.
