I gave my cat catnip once- it was crazy! but he never showed any interest in it after the first time.
Do you think they get a ‘hangover’ from it?
I’m not sure. I know some cats go nuts for it, others are indifferent to it.
The cats we have had over the years have really liked it. Typically, I’ll put a little down on the floor and the cat will proceed to lick it, sniff it, and roll in it. Then they get really frisky and start attacking anything toy or object they see. After the high, they tend to become very docile.
