The Petmate Jackson Galaxy Base Camp Hub with Solid Tunnel was an immediate hit, as you might have seen in our arrival video posted weeks ago (and also posted below). It is a great base camp and expandable cat tunnel combo that is ideal for play - kitties want to go inside and check it out. At least the 4 kitties I used with it did - Caymus (10-year old Ragdoll), Murphy (10-year old Ragdoll), Charlie (5-year old Ragdoll) and Trigg (5-year old Ragdoll) did.The Petmate Jackson Galaxy Base Camp Hub with Solid Tunnel is as exactly as it sounds - a purple base camp with a green tunnel that attaches via a zipper. There are three different "holes" that you can attached the tunnel to. And there is also a zipper door located on the back. So this also makes for a great gift for a kid that loves cats because there are a lot of different fort-like combinations possible.It fully collapses for easy storage, making it ideal for travel or play in small spaces - so that it can easily be packed up and put away. It comes with a little bag...and is packaged in this bag when you first purchase it. This is the storage bag that you use later on - you'll see this in the arrival video below as well as our final review video below.This expandable cat tunnel measures 20 x 11.5 x 12 inches and weighs just 2.7 pounds.You can buy it on Amazon.Here is our arrival video:[youtube]http://youtu.be/HPtVyfKkVNU[/youtube]Here's a video of Caymus and Murphy (10 year old Ragdoll cats playing in the Petmate Jackson Galaxy Base Camp Hub with Solid Tunnel)[youtube]http://youtu.be/vWTbt1BZSR8[/youtube]Here is a video about how to collapse the Petmate Jackson Galaxy Base Camp Hub with Solid Tunnel:[youtube]http://youtu.be/CK6HL7gbhdc[/youtube]Here is our final review video:[youtube]http://youtu.be/UpDHQ1qE2Jk[/youtube]We asked Petmate to make a $200 product equivalent donation to the non-for-profit organization, Kitty City NM, in exchange for the review of their cardboard cat scratchers.
