My two old cat love him more than anything! Keep else really composure when it comes to catnip, especially the one. But when Pawbreaker not - as is already sneaked to the package when it arrives and then the carton, the film and all dearly loved, where the ball was in - to say nothing of the ball itself. Negative side effects (had something, which has a broken then, Weil was probably too exciting or similar) not there apparently also. Which get their kicks and if they are happy, I pack him - well packed up - way up it's that time again. You can take him a couple of times, which is so hard that they can so bite out pieces or no. Sometime just flies by force if they are old. But it is worth the money.
