Each breed of cat takes a different time to reach adulthood. Most cats reach adulthood at one year old, and some large cats take a year and a half or even longer to reach adulthood. Parents can feed the cat according to their own breed. To decide how long to feed a kitten food, a cat the size of a Ragdoll will basically take a year and a half to reach adulthood.

Tip:

Male cats mature later than female cats and are larger in size. Parents should also make a feeding plan based on male cats when feeding them.
