At What Age Are Cats Fully Grown?

The Discerning Cat

For humans we generally have quite obvious milestones for when a child becomes an adult. This could be the age they are allowed to drive a car, drink alcohol, get married etc and across the world this tends to range from 18 to 21 years.

The Discerning Cat

But when is a cat an adult? We don’t have those types of legal milestones for our favourite felines. How do you know if your cat is an adult?

The Discerning Cat

Rapid Growth: 2 to 6 Months

The rapid growth stage begins once a kitten is weaned off its mother. At this stage, the kitten needs lots of nutrients to support its fast rate of growth.

Adolescence: 6 to 12 Months

Your cat’s growth will begin to slow down during this stage and it can be moved to 1 to 2 meals a day. Kitten food is still the best option for cats in this phase as despite their growing size they are still in need of a high level of nutrients.

Young Adult: 6 months to 2 years

This is the phase during which your cat moves from kitten to adult.

Prime Adult: 3 years to 6 years

Cats are settled into their lives and in their prime.

Mature Adult: 7 years to 10 years

Cats tend to become less active during this time and health issues more likely to arise.

Senior Cat: 11 years to 14 years

The life spans of cats vary quite a bit but this is essentially old/older age for felines.
