Review on Pop-Up Play Tunnel For Cats In Blue With Rainbow Design - Collapsible Cubes, Pack Of 1 by Steven Darkshnar

I have 6 cats (!) They have 'played to death' 3 previous cubes and wouldn't wait for me to put this together before jumping into it. It is a source of constant fun & amusement. The baby discovered that he could pull one end over the floor vent and get the warm air to flow through it, so he likes to take his nap in the warm tunnel. They drag it all over the house. The only problem with it is the way the cubes connect to the tunnel. There are velcro tabs on the cubes, but they don't line up with anything on the tunnel (or each other) so they are totally useless. There are several strings to tie the cubes to the tunnel, but they leave big gaps. Very poor design. The cats don't mind, though, because they can take the short cut through the gap. All in all, this is a great cat toy. I would purchase another one (will probably have to in a few months!)
