I think if cat toy companies used Kitty as a toy tester, then they would really know for sure if their toy was a big hit or not. You can get her attention at first but she may lose interest fast if she doesn’t really enjoy it.
Here is a video of her with one that is usually popular with cats:
She did eventually play with it a little but lost interest soon enough. Maybe it’s an age thing, where the younger cats would have more fun with it or just laziness on Kitty’s part as rather do some birdwatching or something along those lines.
I wonder if she might like the Angry Birds game.
Oh well, I guess just have to try one by one, until find the right toy she really likes.
