       | If the side-effect of getting this stuff on their fur while
       | getting all frisky and euphoric from its psychoactive effects
       | conferred an evolutionary advantage, it's not that they _want_ to
       | impregnate their body with the smell.
       | 
       | They're just seeking pleasure, they don't know jack shit about
       | what plant chemicals are increasing the survival of their
       | species. If the cats that liked the beneficial plants survived
       | better, guess what, more cats like getting high in the long-term.
       | 
       | It's disappointing to see "an animal behaviorist at the
       | University of Pennsilvania" making such a glaring error.

         | AFAIK, catnip is first attested in Italy, and I have not seen
         | anyone discuss finding a lot of catnip in the historical ranges
         | of Felis lybica, that domestic cats come from; how can they
         | have evolved to exploit the benefits of catnip if it's _not
         | there_ while they are evolving? Seems like you 'd need a lot of
         | wild catnip for such a selective behavior to evolve, but in the
         | deserts where they live, there might be none. (Catnip isn't a
         | particularly desert-tolerant plant.) Then you have the fact
         | that something like a third of cats are immune to catnip & it's
         | highly heritable, even though if it's a good insect repellent
         | (that's quite fitness-relevant), there's really no reason for
         | it to not have reached fixation quickly and become a 100%
         | frequent trait. Further, catnip response across all of the
         | Felidae species is super-inconsistent, with very far flung
         | species showing some catnip response but also closely-related
         | species showing very different responses; if it's under
         | selection, they ought to be similar, and anyway, there may or
         | may not be catnip where Felis lybica grew up, but then what
         | about South American felines half a world away...? Finally, if
         | you feel that you need an evolutionary explanation, then what
         | is your explanation for all of the other cat psychoactives like
         | valerian, Tartarian honeysuckle, silvervine, the Indian one,
         | and so on? If you don't think there is one, and that, like most
         | human psychoactives, it's just because biochemistry is really
         | complex and stuff happens, then surely that shows catnip didn't
         | need one either.

         | 
         | How do you know? Many animals, including cats, are capable of
         | thinking strategically. Cats in particular are very aware of
         | scents. I don't know all the reasons they roll in catnip, but
         | don't see why it's absurd to think that they do it partially
         | for self preservations reasons.
         | 
         | Similar to this, cats will often rub against their humans after
         | they return home. They specifically rub scent glands against
         | their human to add their own smell back into the mix with all
         | of the new ones.
         | 
         | It doesn't seem like a large leap to think they alter their own
         | smell for practical reasons beyond getting blitzed.

           | It's not about cats having knowledge of what's good for them.

       | Really interesting, so you get high and get bug protection, win-
       | win! Sadly my cat has no reaction to any of these that I've
       | tried: catnip, silver vine, and one other herb I'm forgetting
       | (Japanese maybe?). Maybe he's secretly a kid from the nineties
       | and took the DARE program too seriously...

         | Silvervine is Japanese, so that's already listed; you probably
         | tried either Tartarian honeysuckle or valerian. Immunity to
         | _all_ of them is pretty unusual, but it 's also worth noting
         | that responses can be variable, and each one should be tested a
         | few times spread out. (It seems like stress or uncertainty can
         | help shut down responses. Cats are very cagey about showing
         | inner state.)
