It is best to neuter your cat or dog. There are way too many over-populated shelters. And either way, it won't have much effect on the animal other than they won't be able to have babies anymore.
Sometimes they will become "lazy" and could get fat since they aren't roaming around looking for someone to mate with, but if you give them a healthy diet and plenty of exercise they will be just fine.
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.
