When I received this in the mail today I gave (2) of these toys to my cousin who also lives next door he has the brother cat and I have the sister. So I gave him some toys today I gave him a red and orange. I kept the gray,black and pink.
Once my cat smelled the catnip she started going nuts and rolling around on the floor nibbling on the little toy so I know she really likes these. So far so good and worth the purchase.
