Query: Cats love this toy!!!!!

I have 3 indoor/out door cats and one indoor only cat, with only one who won't play with it. The indoor cat thinks this was the best invention ever made with or without cat nip added. The 2 other cats are in love with it, but one of them swears there is an animal going around and around that he must catch and catch it NOW!!!!The indoor cat uses it all the time to scratch with no nip added. I'm surprised sometimes since he really enjoys doing it. The other 2 do not use it since they can find a tree when they are out side a few hours a day.The only draw back is if you put this on a wood floor since it can be loud with the ball whipping around. The problem is corrected if the toy is put on carpet.Oh, do not give up hope if your cat doesn't play with it right away. Just add the nip once and over time they will wonder what that is and figure out the ball moves.Have FUN!!!!!!!
