Cremation is a good option. You can choose a private cremation where you get ashes back, or do a group cremation where you don't get the ashes (this is cheaper). Some cities do have a part of the landfill for pets.
It might not be the best option, but might be there for you.
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.
