Look into WHO and what they own, especially within the domestic pet "care" industry. Then wonder where all the diabetes, allergies, "crystals"- blockages, etc. cases come from. Pet "parents" obliviously shell out thousands, never remembering what they'd learned about these animals in grade school. Carnivores.
It's one rabbit hole NOBODY wants to touch because it hits too close; people conditioned to consider their pets as "furbabies". Glad I don't own any pets.
