Again, NO! Male dogs and cats will reach sexual maturity long before they are totally grown, and can easily “make babies” before their total body growth is reached. Many breeds of cats and dogs will not be fully grown until they are two or three years old, so it is important to neuter them before they become sexually active or frustrated. A lot of the “humping” behavior seen in older dogs and cats is due to them not having been neutered early enough.
