Cats are unsure of this, but hopefully in time they will play with it.

Note the 5 stars! I'm going to explain why I think this thing isn't working for some of you (and one of mine), but why I'm still a fan. I think the trouble folks are having is that this is not the strongest smelling catnip, especially the outer layer. How could it be? It's dried, compressed and oxidized. Second, different cats take to catnip in different ways. I bought two of these. One for my American medium-hair (AMH), who loves catnip when she's in it but doesn't just run to it because it's out. I put that one in her hiding spot and after a few days I could tell that she had started licking it. Now she's wild about it. The other I bought for my Russian Blue (RB). If you cover her up in catnip and act like you aren't watching she will eventually get into it. But she's way too cool to allow anyone to see her having a good time, so she generally acts like she doesn't care about even the freshest. I gave up on RB and tried to give her catnip ball to AMH. AMH has thoroughly destroyed her original catnip ball, but refuses to touch RB's discarded one. My take is that RB's ball smells like RB and RB and AMH live together under under truce, not true love. If your cat doesn't go for the ball immediately, I think it's a matter of making it smell like them or priming it with a little catnip spray so they get the idea. Matter of fact, I'm going to get another and try again with RB and the spray (plus I'll leave it in her spot like I did the last one). Even if she just tolerates it, the science seems to say it's doing her good.

My cats absolutely love this! They don't lick it, but they kick it around the room until it gets lost somewhere. It's a little larger than a golf ball, so it doesn't get lost under some furniture/in some corners like a smaller one that's lost somewhere around here. If I find it, they stop what they're doing and chase and kick it around. Great exercise! I have this on repeat delivery so when they lose one, it's not too long before they'll get another one. Also, I like that it's catnip, so it's not attracting any bugs or critters when they lose it.

The only thing that helps my lazy cat play will definitely be buying more!

My cats absolutely love this, it gets the older ones active and moving as well

Mitsy enjoyed this cat nip ball. She certainly goes to town with it.

He loves it instead of having catnip all over the house it's compact and he goes crazy with it

I bought this because we had one before and the cats loved playing with it!
