Hi Wolfy and Everyone, In reply to the post asking about switching to turkey based kibble (versus the imprinted on chicken based kibble). I was first introduced to the turkey based kibble when Houdini entered my life. What was initially thought to be severe ECE, IBD or a blockage ended up being a severe food allergy. It took a while to determine what he was allergic to and it ends up being chicken. After many attempts to coax him to eat, he started stealing pieces of the Totally Ferret Turkey food. At least he was eating on a regular basis, but continued to exhibit allergy symptoms which included: severe itching, hives covering his head, around his eyes and mouth, thin fur coat, yucky poops and sometimes he would vomit. Although we were having some success with the Totally Ferret Turkey food, it still contained chicken and is only sold in smaller, very expensive bags. The Proplan Turkey and Barley is sold in larger sizes and much less expensive. A wise ferret mom (Donna Connor!) also had a ferret with chicken food allergies and gave me some of the ProPlan Turkey and Barley (cat food) to try. I was hesitant to change his food an upset the little progress that we made but we gave it a shot and he LOVES it. Needless to say once one ferret looks like they are getting something special, the others all started stealing his food to the point where all my other ferrets prefer the ProPlan Turkey & Barley as well, now that is all that I buy. Even my cat whom the ferrets torment and love comes into the ferret room to eat the ProPlan. As well sometimes a coupon is enclosed and if the local pet store is having a sale, I stock up and I buy the bigger size. The containers come in handy for other uses as well as being an interesting ferret toy once emptied. The ingredients are mostly meat based; the protein level is great although the fat content is slightly less than perfect. For some reason the barley is more soothing to the GI tract than the turkey & rice type. Houdini continues to thrive to this day and almost never has any hives (unless he sneaks into a visitor's cage and eats another food). As far as giving it to older ferrets, I have two that are over nine years old and they eat it every day. I also use it to make the duck soup gravy by using a coffee bean grinder (as it doesn't really dissolve in warm water the way say Marshall's does). I add a little AD Feline and they line up in anticipation, practically drooling while it warms up. I would recommend adding it in their usual food a little at a time or try giving it as a treat at first so they think it's something special. All the best to you!
