Same for theobromine in chocolate.
Though I *Wish* caffeine made Me go fast, it's just makes me....tired, but sometimes still enough to focus so I still use it.

That was easy, alcohol is toxic for cats and dogs, other foods like cocoa (theobromine), coffee & black or green tea (caffeine), macadamia nuts, avocados, garlic, onions or xylit are also toxic.

Based on my reading raccoons tend to have lower levels of cytochrome p450 activity
in their livers which would put them at higher risk of damage from xenobiotics like caffeine and theobromine…..with that being said I have no evidence that they don’t have alternative mechanisms for clearance 🤷🏽♂️

I get that this is likely just a bit of fun, but people do not feed your dogs chocolate, it's toxic to them. They cannot metabolise theobromine.

They cannot metabolise theobromine, they need prompt treatment because it can induce vomiting, diarrhea, seizures and worse.
Dogs are scavengers sure, but like all scavenger animals they don't just eat everything they lay their eyes on.

"A natural chemical in dark chocolate may play a role in slowing certain signs of biological aging. Researchers at King's College London have identified theobromine, a plant compound found in cocoa, as a possible contributor to this effect."
Scientists have uncovered a surprising link between dark chocolate and slower aging. A natural cocoa compound called theobromine was found in higher levels among people who appeared biologically younger than their real age.
