'Wonder whether our feline companions (Tiny above in her cups) and catnip (Nepeta cataria) evolved together through the eons of Darwinian natural selection? What does the cat or the weed have to gain from their association? Is it just one of those things, a happy accident along the road of the relentless drive to continue the bloodline? More thoughts at our May 2005 post "Substance abuse, then and now."
Just one of those those crazy flings …
A trip to the moon on gossamer wings Just one of those things.
When cats smell catnip they exhibit several behaviors common to queens in season (females in heat): They may rub their heads and body on the herb or jump, roll around, vocalize and salivate. This response lasts for about 10 minutes, after which the cat becomes temporarily immune to catnip's effects for roughly 30 minutes.
Same behavior observed in the Chelsea Grays in response to Tuck's cat whispering. Tuck Willis knows what cats like.
Update: More of those crazy flings at Modulator's Friday Ark #240, now boarding.
