Do they make human equivalents???
Of course my young cat went mad - see the photos other customers have sent in - but I was amazed that the old rescue cat, who doesn't play with toys, went bonkers mad right away. When I first got him, I gave him a valerian toy from Zooplus, which he kept for over a year as a "comfort" (his situation had been extreme). This toy contains valerian too, plus cat nip and some thing called "silver vine". It is also MADE IN GERMANY like lots of Zooplus products, which is reassuring.
