I use it too. I picked up a 30 lb bag at the last show from one of the
shelter. However if you contact Zupreem by e-mail they will send you
retailer that handle it (both local and Internet). Just go to their
web-site and click on contact us. Our local Petsmart carries it, but
it's expensive.
On-line Ferret Depot seems to have the best deals.
Hope this helps
