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.
You read this correctly, this is a dog toy. That is not stopping us, or your cat for that matter. Fill IQ Ball up and it is not too difficult, but fill only the opaque side and utilize the internal divider with adjust-ability options and you can increase the challenge level!
The only downside is that the opening has a slightly irregular oval shape and will not work for larger pieces of dry food.
