A disease that did not exist before 1979. A chemical policy implemented four years earlier. A piece of cat biology thirty-five million years old. The forensic case behind the pet bed problem.

In this episode, we debate: is a compelling correlational case — built from a specific timeline, a specific mechanism, and a specific species biology — enough to act on, or does the absence of proven causation mean the honest answer is still \"we don't know, and we should wait\"?

We unpack five concepts you will need before reading the article: The 1979 Inflection (a fifteen-fold rise in feline hyperthyroidism in six years, aligned with California's TB117), the Evolutionary Chemical Mismatch framework (ancient metabolism meets new chemistry, applied to dogs, birds and fish), the UGT1A6 Pseudogene (why cats — and every lion and snow leopard — cannot clear phenolic compounds), the Species Boundary (where consumer safety law ends at \"the subject must be human\"), and the Correlational Ceiling (the honest limit of the case we can currently make).
