This seems like it'd make for a very happy cat, but that level of sodium and caffeine and any alcohol intake at all has to be pretty bad for them.

I've seen his story across various sources - has he ever elaborated on specific quantities/ratios? I haven't seen anyone reproduce his regimen for his cats, and I'd love to see some more concrete evidence that the diet is effective (IMHO the extensive development of his home to act as a massive jungle gym feels like the more likely culprit in their longevity).

Thanks for sharing that article, it was a great read
