I currently have a foster cat that was found and never re-claimed - slated for euthanasia.
She was flea ridden, malnurished, rhino and yes...pregnant. She is proof that cats cannot sustain the outdoor elements without human intervention. They do rely on us for their survival.
This cat WILL live, though her babies to be will not. She must endure surgery to spare any further animals that she carries any pain and suffering in the future.
Thank you for such a powerful and educating post. It could not come at a better time.
