Pros: Great cat/human interaction, fun crinkle noise, lights up, fun "lookout hole" on top! , sturdy frame.
Cons: None at all for us!
This is a great toy for us. I play a lot of games with Speedy using this toy. She loves when I dangle a toy through the hole on the top, also you can throw a ball and she will chase it through the tunnel. Whenever the cat goes through it, I love the fun crinkle sound and if the kitty goes through with some speed, the tunnel flashes! Our favorite game is when I lie (or hide) on one side of the tunnel and Speedy is "hiding" on the other, I will slowly slide my hands under the width of the toy to the other side and when she sees my fingers appear, she pounces with such force on the tunnel, it lights up and the crinkle noise is great! I just have to be prepared because sometimes she pounces with a lot of force!
I imagine this would be a great toy for cats to play together with. It is lightweight, but very sturdy frame and the flashing lights are still working! The toy can be collapsed for easy storage, but mine is always out for play. I love the crinkle fabric, it is very durable. I simply vacuum it with a brush attachment from time to time.
My only regret is that it was not available in the lime green pictured above, I would have loved that. Ours is navy with burgundy trim, but it is still a wonderful purchase!
