Is this exact substance present in Valerian root as well?

i know valerian is loved by cats,maybe more than nepeta as far as i seen but i don't know valeriana contains others substances as valepotriate valerenic acid and others

Have you gave both of plants to cats? does both produce exactly the same "high"?
Do you think cats trip on these plants? (especially valerian root) or simply just get high?
To me, a cat on valerian seems like she's having an intense but short trip, like a DMT or Salvia trip. I've not seen a cat's behavior on catnip yet.

it seems they have a sexual behaviour when they smell the plants,expeciallly with valerian imo,this is for my cats,he doesn't react particularly strange with catnip

My cat goes crazy. Like it's a stimulant of some sort. Rolls around in it, eats it, then runs around like a pack of wild dogs are chasing her. When I pet her, she'll be nice for the first few, then she'll start getting all excited and biting and scratching my hand like it's a toy. I also think it's like a perfume to them. Hence why they roll in it. It would certainly attract other cats.
