These foraging balls are a great beginner toy. They also are great for down the road when your cat becomes a "master forager" and it is time to increase the challenge. As shown in the photos below, these balls can be placed inside larger containers much like the foraging ping-pong balls from Fundamentally Feline are utilized to increase the challenge. One never needs to get rid of easy toys, just save them for later when you need to make the game harder.
Foraging toys do not need to be fancy. They simply need to vary to continually peak your cat's interest and be appropriate for their skill level. Remember that foraging is not just a feeding protocol but also mental stimulation for your cat.
The goal with this toy is for the cat to either shred the bag with their claws and teeth or to open it and use their paw to extract the food.
