If you’ve just gotten a kitten, you may be wondering, “how long do cats grow to reach their adult size?”
No matter the kind of cat breed, from Sphynx to Siamese, your feline friend is sure to grow as big as they possibly can.
Your cat hits similar developmental milestones to a human baby in its lifespan. However, if you’re wondering, “when do cats reach full size?” you might not find a definitive answer.
The average kitten weighs around 3.5 ounces at birth. They usually double in size during their first week, after which they’ll grow about an ounce approximately every three days.
Kittens typically grow eight times their size in just about eight weeks.
Because kittens grow at such a rapid rate in their first few weeks, you’ll notice they eat quite a lot of food.
The right time to transition your cat from kitten to adult food starts around 10-12 months of age.
Some cats reach full size anywhere between 18 months to 4 years of age, so it’s hard to say at what age a cat is fully grown.
