I've used a Catquiver for at least the past 15 years, but stopped using the actual Catquiver packs/backpacks years ago. In my opinion, they are junk.
Simply take the quiver portion of the Catquiver (I believe they market it as the Mini) and attach it to the pack of your choice. There are tons of options (Badlands, Tenzing, etc.) for packs that are FAR more usable than the fleece pouch that Catquiver tries to pass off as a pack. You can customize fit/location of the quiver portion by using zip ties or (what I use) stretch cord to securely fasten to your pack.
I use mine with my KUIU packs- friends have theirs on any number of different makes and they work great- far better than any of the Catquiver options.
