Here is an inexpensive and simple toy that cats really like to play with. My cats watch with rapt attention as I open the pack and take out one of the mice, swing it by the tail, and scoot it along the floor. Then a cat who had been hiding out comes streaking out of nowhere to pounce on the prize, and carry it about in his mouth. Then I toss another to the other ones waiting, and they bat it back and forth as if playing soccer. These toys often end up out of paw reach and out of sight until I find them when sweeping under the refrigerator, and the cats react happily because their toys were rediscovered. I think this is why they come in bright colors. To help humans find them again. Others end up being chewed and eaten, and this is safe for the cats to do. Anyway, this is simple fun entertainment for the hunter instinct in our cats, and it makes mine very happy. These toys are worth it even if they get gobbled up because they are inexpensive to begin with.
