A neighbor received one of these in a cat "theme basket" at our church. It was hilarious watching her cat play and jump in this thing. Well, the long and short of it was that we went out and purchased one and enjoyed watching our cat have the same enjoyment. What is it about the crinkly sound that they love? Will never know, but this provides hours and hours of fun.

Pros: Everything

Cons: None

Malford loves to sleep in this. A little noisy, but once he gets in he loves it. Great for napping.

Pros: warm

Cons: none

We purchased a crinkle tunnel mainly because our one cat would love to get into the grocery plastic bags when we came home from shopping. Turns out, that cat avoid it, but the other cats love to play hide and go seek using this tunnel.

Pros: crinkle sound attracts

Cons: crinkle sound may deter

This thing terrified my cats so much they wouldn't go anywhere near it. I finally gave it away to a neighbor.

Pros: Looked like fun

Cons: scary

I think all of my cats like this except the big old cat. But the others take turns crashing through it at warp speed and putting their toys in it and diving in after them

Pros: Easy to move around when I vacuum

Cons: Cant think of any yet!
