Same Chemical in Sauvignon Blanc Wine and Cat Urine

Felinine is an amino acid found in cat's urine. 3-Mercapto-3-methylbutan-1-ol (MMB) is a product of the degradation of felinine. MMB is a thiol and believed to be a cat pheromone found in cat's urine.

MMB is also found in Sauvignon blanc wines, which are gooseberry flavoured. Thiols contribute to the aroma of Sauvignon blanc wines.

Interesting, I think. We usually can't smell cat pheromones. We can smell the aroma of wine however.

No idea what more I can say about this except I am surprised ;) Follow up post on main site.
