Hello; This is something expected for some years. At least I wondered when someone would make the connection public. Someone finally did so. From the start let me say I do not have a dog in this fight, nor a cat either. So, in real terms I can be neutral and perhaps I will be.
The gist revolves around all the meat dogs and cats eat and the associated things needed to produce dog & cat foods. A summary goes sort of there is impact to starving people and the environment form all the meat production which winds up in dog & cat food. General details in the above link if you need to know more.
A crux of the matter is cats specifically and dogs nearly so need meat protein. From a physiology view point a look at the gut of these animals will tell the tale. Can take a look at the teeth for confirmation. That dogs & cats need meat should not be debatable, but this site does surprise me often.
Anyway, the nature of these revelations has led up to cries to change the way we live often. Think of the agendas against domestic cattle as an example.
So do you favor getting rid of dogs and cats or maybe just cats as pets?
Do you fall on the side of keeping dogs and to heck with all the hungry people?
Is there another lane to be in?
I will try to be impartial as I do not have neither a dog nor a cat.
SIDE NOTE- this would have been posted in the off-topic thread which remains closed. Such a shame to close that thread.
