Megan O'Shaughnessy DC <[log in to unmask]> asked: >My questions are: Is this closure sufficiently ferret-proof? Megan, We've only had two ferrets so far who could manage to get these open... but you never know when another one will figure it out! Securing a clothes pin (spring-loaded wooden kind) to one of the vertical cage members just above the sliding horizontal bar has foiled them completely. A spring latch such as the kind used on dog leashes (or a carabiner) can also be used to latch the sliding bar to the fixed horizontal bar on the door. Just depends on what you have lying around the house, I guess. Hope this helps, ellen & the Gang of [for the moment] Three [log in to unmask] [Posted in FML issue 2426]
