How old does a male cat need to be to father a litter of kittens?

Yes. You need to spay or neuter either one. The male will definitely spray.

Trust me you do not want to live with a female cat in heat. You do not want to add to the unwanted kitten population either.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
