hi again, I have two questions, if anyone could help me out I would appreciate it. Ok, first, I was wondering what is the difference between Yesterday's news and Marshall Ferret litter. It seem the same...is one better? Next is, I was wondering if you change hammocks in the summer. Banx has a fleece hammock that she can crawl into to be covered, should I use a cooler one for the summer, or leave the fleece on up? Thanks for your time. Dooks and Hugs to all ...sorry to those who lost a ferret Laura and Banx [Posted in FML issue 2985]
