Hi, I have a great small carry sack on auction at Ebay if anyone is interested. It has a zipper closure, much more secure than those velcro ones you find. It fits an individual ferret great. I used it when I would have to take just one of my ferrets out, like to the vet for booster shots. It is Item # 2006970827. All the money goes back to the ferrets to buy some new harnesses so when spring comes we are ready to go the park. Thanks, Kiffany [Posted in FML issue 3710]
