Is there mescaline in a cats brain?

Answer 1

In a cactus. not in a cat.

There is a small amount of mescaline in peyote and a few other cactuses.

In the 60s and 70s, scientists performed abusive experiments on cats, injecting mescaline or other hallucinogens into them, then trying to measure how the drugs break down in the brain and body. There is an old article called "DISTRIBUTION AND METABOLISM OF MESCALINE-C IN THE CAT BRAIN." this does not mean cats naturally have mescaline in their brains.
