I am so pleased that I tried the CrackleChute. Not all cats may be entertained by it, but the ones who love to play will love it. I tied two together and my Josephine thinks it is just a blast to run from one end to the other. She doesn't really meow, but she does squeak and she lets me know she wants to play by sqeaking at me and running to the tunnel. I dangle a ribbon in front of one opening and she runs from one end of the tunnel to the other. One of my other playful cats loves the tunnel too; sometimes he just takes a nap in it. The tunnel is extremely durable. After I purchased the first one, my cats and I loved it so much I purchased a second, and I just bought 2 for my sponsed shelter.

Pros: durable, provides entertainment

Cons: takes up space

Smitty loves this tunnel. It reminds me of a plastic shopping bag crinkle sound. He will spend hours laying in the tunnel. He runs through it, bats his mice into it. It is entertaining to watch him. Oscar, the dog, gets real uptight when Smitty is playing with the tunnel.

Pros: inexpensive, durable, entertaining

Cons: none

Seemed like a good idea, but my cat wasn't interested. I think he'd rather just have a cardboard box.

Pros: Bright color

Cons: None

Got this for the three kitties in the house. First they wouldn't go near it, then they each took turns exploring it, then ambushing each other. They don't use it so much anymore, but do so on occasion.

I think they would like it more if the diameter was larger so they could move through it faster.

I like to put catnip in it--they like that too :)

Pros: easy to use and clean

Cons: moves around if unanchored, short

The shelter kitties love these things. They get a lot of use, and occasionally one will get a small tear. But, for the price, the cats get a lot of enjoyment out of these things.

Pros: Lots of fun for playful kitties

Cons: Eventually tears with rough play
