I assume, from searching the FML archives, that ferrets can get heartworm, that they should be tested, and that they can be put on preventative. (right?) Does anyone have a list of which animals can get heartworm and which cannot? (I guess I'm not clear what constitutes a susceptible animal. Dogs/cats/ferrets...anything else?) Also, can ferrets get FIV from an infected cat or is that specific to felines? I saw a couple of new products and was curious what opinions of them ferret-knowledgeable people would have. First, Jeffer's Pet Catalogue shows springs that you put across corners in a ferret's cage to stop them from 'backing' into corners you want to keep clean. I rather doubt they'd work (I think my ferrets would leave a pile right in front of the spring if they so desired), but do you think they're safe or worth suggesting to people who are having litterbox difficulties? The other is Zoo Med's Can-o-Products, such as Can-o-worms, Can-o-grasshoppers, Can-o-snails, etc., which are all dead foods. They're newest display lists most of them as suitable treats for ferrets (as well as cats). Do you think a ferret would like them, and are there advantages/disadvantages to giving a ferret a bug as a treat? Kara (& the 13 Co.) [Posted in FML issue 3794]
