Make it Mandatory to have ALL pets spayed,or neutered in every state

I am asking that you please make it mandatory in your state for all pets to be spayed,or neutered unless they have a breeders license.The overcrowding, and killing of thousands of loving animals a day,that were once pets,and now unwanted by the people who were so careless as to let their animals breed.These poor animals are euthanized,or gassed inhumanely (some still alive after the gassing) then stuffed in drums,or plastic bags waiting to go to the landfill.They did not ask for this cruel ending,all they ever wanted was to have a home,to be loved, and to please their owners,then were betrayed by the people they once trusted to love them for life.If every state would come together and make this a law, the killing would stop.
It was the ignorance of society that has let this happen, now we all have to come together to fix this,please let it start here.
