I understand you so well, I go through the same with my cat so that’s why I am constantly innovating regarding cat games lol. My last successful toy now is a feather attached to a piece of dental floss with a stick lol. You can’t believe how much my cat plays with this, but I have to use it wisely because if I overplay with it, Sophie will get bored. Another idea I am having is purchasing these moving fish toys, I have seen that a lot of cats engage with these toys so I am thinking about getting one. I will post it on this review if this is idea is a winner. Don’t feel bad, some cats just need much more incentive to start playing than others. My cat Sophie is one of them and I am sure yours is too. I will post the video of my cat playing with the feather and dental floss as string, I shot the video not long ago. I hope you can find a solution for your kitty, hope that helps!
