One of my cats will hide in the tunnel and the other (or others) will be waiting outside to pounce on the one inside. They also like the loud crackling sound these make. I took two and pinned them together for a longer tunnel.

Pros: Hiders and Pouncers Love These

Cons: Noisy; need to be longer

We all know a cat likes even the sound of paper being rolled up - with this they can hide and play and hear that sound even when you aren't around

Pros: Simple toy

Cons: None

It all depends on what your cat likes; We have two cats, one loves this toy and the other hates it. If your cats like to try to get into plastic grocery bags as soon as you get them in the house, they will love this tunnel. Also, this toy is convenient because it compacts for easy storage if you need to get it out of the way.

Pros: Some cats love the crinkle noise

Cons: Some cats hate the crinkle noise

I like to watch kitties play with this. Is pretty amusing.

Pros: n/a

Cons: n/a

This is the best! Our cat's spent hours playing in, on and around this toy. It does come in many colors. It is a loud toy, but so enjoyable for the cats that it's worth it!

Pros: cat's loved this!

Cons: it's noisy
