best ways to keep indoor cats entertained

I've got two indoor cats, and I've found keeping them entertained is a constant challenge. Anyone else feel the same way? I've tried a few things that worked pretty well, like rotating their toys every couple of weeks to keep things fresh and interesting. They also love chasing the red dot from a laser pointer, and it's a great way to get them moving. I recently discovered that they go nuts for a cardboard box or even a paper bag. It's like magic—instant cat trap! 🐱📦 I'm curious what others are doing to keep their feline friends happy and stimulated indoors. Any unique toys or activities that your cats adore? Let's swap ideas!
