My cats just love the cat triple expandable tunnel. In the center where the 3 tunnels come out, there is a hole where they can either put their head out or you can dangle toys in for them to play with. They seem to enjoy sleeping in it too. Sometimes when I can't find them, I check to see if there is a lump in the tunnel. It does take up some space, but if it keeps the kitties occupied, it's worth it. I have been very satisfied with this product.

Pros: Fun for cats, room for multiple cats,low cost, sturdy

Cons: takes up space

This is an inexpensive cat toy that you can get at most discount stores. The one I have has a crinkle mat inside that makes noise when they walk on it. The best part is the opening in the side where they can poke their heads out and bat at their friends on the outside.

Pros: Kittens love it

Cons: None

Some kind soul donated one of these to the shelter. The cats love it. Thanks to whomever donated it.

Pros: Pretty and fun

Cons: takes up a little space on the floor
