It seems plausible that those nutrients might be found in certain plants, and could be identified and concentrated. I wouldn't risk it with my cats, but plenty of people do feed their cats veggie kibble and I haven't heard of them dying of malnutrition in droves.

IIRC the nutrient that makes cats obligate carnivores is taurine. Although it can be found in seaweed, or synthesised in a lab, cats and water makes me think this is unlikely in nature. (That said, human edible != cat edible, don’t just feed seaweed to your cat without asking an expert).

Or energy drinks.

Stimulants — or drugs in general, legal or not — should definitely not be assumed safe on a different species.

(Also: not all energy drinks are vegetarian, so wouldn’t always solve the diet puzzle even if you confirmed it as safe).

My cat refuses to drink Monster, but insists on Red Bull Blueberry.

They are finicky creatures.
