My old roomate used to grow catnip for his cats - I think he thought that cat was jealous of the humannip he grew from himself.
they'll just pick it up from some stray cat that has done every pet in the neighborhood (including the ferrets) Please people, don't let them get it on the street!
yea the cat nip they sell on the streets is often cut with really deadly things. that's bad news there.
this is for those who support their cats' catnip habit...... an easy way to make a catnip toy for your addict cat......take a shoulder pad, (who wears those things anyways?) and fold it like a taco....stick the nip in and then sew it up.....easy stuff.....
