Christ(opher) Sign. 45.
It's a sign: someone is rising 'from the dead'
Cats are obligate carnivores and have to have taurine in their diet to survive. In nature, this comes from the hearts and brains of whatever they kill. A cat on a diet of raw meat must have heart / brain included in the mix.
Cooking meat destroys taurine. The early pet food industry didn't understand this but discovered it when cats were becoming sick and dying. Taurine is now added to petfood after the cooking process.
This experiment needs to be repeated but without the use of cats.
