Hi, I can't find the posting, but someone wrote about thinking Totally Ferret (or was it Marshall Farms) food was causing runny stools. I happened to notice that they also mentioned they might be a little heavy-handed serving treats. I suffered from the problem in feeding my girls Linatone, which made their stools runny until I backed off. This person mentioned Linatone as one of their treats, so I guess I'd suggest easing up on that and seeing what happens. I've never bought Marshall Farms food because I don't want to support their practices (not to mention I haven't run across it on the West Coast). I've never heard anyone mention not buying it for this reason, though. I don't know what MF people do in their breeding facilities, but I do know what they do in shipping ferrets, and I don't like what I've heard first hand. There's some things I do know for fact about their practices (such as early spaying/neuterig), that warrant me not supporting their endeavors. For me, there's enough good food out there to skip food bearing their name, whether or not it goes toward funding them. Just had to say that (sorry BIG, don't want to start another Marshall Farms flame fest). Lynn Mc. and her ravenous Gang of Seven (currently dining on Lavian mixed with high-quality cat and kitten foods) By the way. I know many people mix ferret chows, such as Mazuri and Lavian with high-quality cat foods. Should only high-quality kitten or growth-formula cat foods be used (mixed with ferrt chow), as opposed to maintenance cat foods, to keep the protein/fat levels high enough for ferrets? Or should the growth cat formula/ferret chow mixture be reserved for nursing, pregnant, old, and young ferrets. Thank you, Lynn Mc. [Posted in FML issue 1473]
