Do male cats grow bigger than females?

Male is neither better or worse than female - they are different. Neither is more loving/affectionate than the other. The nature of a cat can depend on it's treatment as a kitten (the same as a child). A female cat (Queen) will quickly fall pregnant if not neutered - over and over again. A male (Tom) will spray (to mark territory) if NOT neutered and the smell is difficult to remove (amonia). Un-neutered males will not not stay close to home - they go looking for a mate and can travel miles and miles. Females are sometimes bullied by males as they are smaller and lighter but can usually hold their own (besides, in a fight, there is always more noise than action).
