tips for keeping indoor cats entertained

I've noticed my cat, Whiskers, has been a bit bored lately, especially with the cooler weather keeping us inside more often. I've tried the usual toys and scratching posts, but they don't seem to hold his attention for long. I've started hiding treats around the house to turn meal times into a bit of a scavenger hunt and it's been a hit! Also, cardboard boxes are a lifesaver. A simple box can provide hours of entertainment. Does anyone have other creative ideas to keep indoor cats happy and engaged? Would love to hear what works for your feline friends! 😊
