Our son recently put an empty fish tank down on the floor - all it had in it was gravel and some rocks. Well, the psychotic sixsome went roaring into his room and jumped straight into it. What fun! They snorkled and dug in the gravel and, being high sided, all the mess stayed in! They all had a ball, taking turns to go in and out, and I enjoyed it as they didn't get dirty feel or noses like they do when they tunnel in sand or earth. I think Nick has resigned himself to having an empty fish tank for a while! Hugs to all your furpals from their Aussie friends. Nona The Ferret Centre [Posted in FML issue 1912]
