People have a clear distinction in the different stages of our growth. Normally, we become adults when we turn 18, and we can say that we officially enter the “adult” column.
How is the issue with the growth of the feline members of our family? When do they enter puberty? When do they become adults? When can we feed them food for adult cats?
There is no specific age for cuddly pets when they reach adulthood. Our purring companions go through different stages of growth. Although there are no clear boundaries, there are still a few general moments when most temperamental representatives stop growing and reach adulthood. Let’s look at them.
When do kittens stop growing?
Cat growth is not only affected by the breed, but also by the diet. Kittens must consume a sufficient amount of daily calories in the first months, otherwise their growth may slow down.
As a general rule, babies stop growing when they are one year old. However, there are exceptions to every rule. While many cats stop growing at 12 months, this is not true for all cats. Some pets can continue to grow even after this period, but at a very slow pace, usually 12-18 months. This is when you can expect your cat to have reached its full adult size.
Large breeds grow at a much slower pace. Maine Coons or Siberian cats, for example, only reach their full size after they are 2 years old.
Did you know that there is a difference between physical and sexual maturity?
Many owners believe that once a cat starts to show sexual behavior, it is already fully grown. However, in reality, sexual and physical maturity do not occur at the same time. Sexual maturation can begin as early as 4–6 months in females and around 6–9 months in males. This means that the animal is already capable of reproducing, but its body has not yet reached its final size and development.
Physical maturity occurs later – for most cats around 12 months of age, and for larger breeds even after 18–24 months. Bone structure, musculature and general physique continue to form after the first heat. This is why veterinary specialists recommend not to rush to conclusions that a cat is “old” just because it shows signs of heat. True growth is a gradual process that includes both hormonal and physical changes.
What happens after a cat turns 1 year old – behavioral changes
After the age of one, most purring animals enter the stage of “young adulthood”. Although they may still be playful and energetic, their behavior begins to stabilize. The hyperactive outbursts typical of kittens gradually decrease, and games become more controlled and purposeful.
Many owners notice that their pet’s character is finally formed during this period – the cat becomes more confident, more territorial and more clearly shows its preferences. Some animals begin to seek more peace and routine, while others retain their playful spirit for years to come. The metabolism also slows down slightly, which means that it is important to monitor weight and adapt nutrition if necessary. This is the moment when the cat is no longer a baby, but is still at its most active and vital period.
Main stages in the growth of purring animals
Here are some important stages that kittens go through as they become adult cats:
• 3-4 months: Baby teeth begin to fall out and are replaced by permanent adult teeth. This process is usually completed by 6 months of age. This is roughly the time when the kittens grow the fastest and change dramatically.
• 4-9 months: Meowing animals go through sexual maturity, coming into heat for the first time. If they live among other unneutered cats (as is the case with street cats), this is the time when females can even become pregnant.
• 9-12 months: The cat is almost fully grown. During this period, it is important to play with your purring animal so that it can feel happy and confident. By the time they reach 1 year of age, most representatives reach their full size. The exception is large breeds, which grow up to 2 years.
• 3-6 years: This is the stage when cats are in their prime. They are grown up and confident.
• 7-10 years: During this period, purring pets become less active and more likely to gain weight. They may develop health problems. Care and exercise are especially important.
• 11-14 years: Life expectancy varies among breed types. We can say that these are “old” cats, whose health could slowly deteriorate.
